The second protein to have its structure determined, after myoglobin, by X-ray crystallography, in 1965.

Breaks up peptidoglycan present in the bacterial cell wall, which is thicker in Gram-positive bacteria, which is what this enzyme seems to target.

Part of the inate immune system.

It is present on basically everything that mammals and birds excrete, and it kills bacteria, both of which are reasons why it was discovered relatively early on.

Generative syntax is a framework within the field of linguistics that focuses on understanding the structure of sentences and the rules that govern their formation. It is a key component of generative grammar, a theory primarily developed by Noam Chomsky in the mid-20th century. Generative syntax aims to describe the implicit knowledge that speakers of a language have about their language's structure, enabling them to produce and understand an infinite number of sentences, including those they have never encountered before.

A bidding fee auction is a type of auction process where participants must pay a fee to place a bid on an item. This fee is typically a small amount, which is paid each time a participant submits a bid, regardless of whether they win the item or not. The concept is often utilized in online auction platforms and can take various forms, such as penny auctions or pay-to-bid formats.

Biosemiotics is an interdisciplinary field that studies the production, interpretation, and communication of signs and meaning in biological contexts. It combines insights from biology, semiotics (the study of signs and symbols and their use or interpretation), and philosophy to explore how living organisms create and interpret signs, as well as how this process contributes to their survival and evolution. At its core, biosemiotics posits that life is fundamentally about information processing and communication.

In the context of number theory and combinatorics, the term "genus" is often associated with the study of mathematical objects like curves, surfaces, and topological spaces rather than directly with multiplicative sequences. However, when discussing multiplicative functions or sequences in relation to generating functions, one can invoke the concept of genus in a more abstract sense, particularly in the realm of algebraic geometry or combinatorial structures.

"1979 Software" is a company known for developing classic video games, particularly in the arcade genre. Founded by David Ahl and based in the late 1970s and early 1980s, the company is particularly recognized for its contributions to the early gaming industry. They developed notable titles such as "Vectorld," which was one of the first vector graphics arcade games, and "Stellar 7," which became popular during the time.

"1988 software" can refer to multiple things depending on the context. However, it might commonly refer to software or technologies that were prevalent or developed in the year 1988. The late 1980s was a notable period in the evolution of personal computing and software development, marked by innovations in operating systems, applications, and programming languages. Some notable software and developments from that time include: 1. **Microsoft Windows 2.

A Program Temporary Fix (PTF) is a solution or patch provided by software vendors to address specific issues within their software products. PTFs are typically released to correct bugs, enhance performance, or add new features temporarily until a more comprehensive or permanent update can be deployed, such as a full version release or major software update. PTFs are commonly used in various software systems, including operating systems, applications, and enterprise systems, and they are especially prevalent in mainframe environments.

The Bockstein spectral sequence is a mathematical tool in the field of homological algebra and algebraic topology, particularly in the study of spectral sequences. It arises in the context of computing homology and cohomology groups with coefficients in a group or ring, especially when the coefficients can be viewed as a module over a more complex ring.

The Boeing RC-135 is a military reconnaissance aircraft developed by Boeing for the United States Air Force. It is part of the larger family of RC-135 aircraft, which includes variations designed for different intelligence, surveillance, and reconnaissance (ISR) missions. The RC-135 was originally based on the Boeing 707 commercial airliner but has been specifically modified for military purposes.

Boom Overture is a supersonic passenger aircraft developed by Boom Supersonic, a company focused on aerospace engineering and aviation technology. The Overture is designed to travel at speeds of Mach 1.7 (approximately 1,304 miles per hour or 2,095 kilometers per hour) at cruise altitude, significantly reducing flight times compared to conventional subsonic airliners.

The Boué–Dupuis formula is a result in the field of stochastic analysis, particularly in the context of large deviations. It provides a methodology for determining the asymptotic behavior of certain functionals of stochastic processes. The formula is useful in the study of complex systems and processes that exhibit stochastic behavior, such as random walks and diffusion processes.

The Bradley–Terry model is a probabilistic model used in statistics to analyze paired comparisons between items, such as in tournaments, ranking systems, or voting situations. The model is particularly useful in scenarios where the objective is to determine the relative strengths or preferences of different items based on the outcomes of pairwise contests.

Bridge disasters caused by tropical cyclones refer to structural failures or significant damage to bridges as a direct result of the extreme weather conditions associated with tropical cyclones. These storms can produce high winds, heavy rainfall, and flooding, which can compromise the integrity of bridge structures in several ways: 1. **High Winds**: The intense winds associated with tropical cyclones can physically damage bridge components, such as railings, deck surfaces, and supports.

A British Thermal Unit (BTU) is a unit of measurement used to quantify the amount of heat energy. Specifically, it represents the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit at a constant atmospheric pressure. BTUs are commonly used in various fields, such as heating, ventilation, air conditioning (HVAC), and energy production. For instance, HVAC systems often have ratings in BTUs to indicate their heating or cooling capacity.

Cameco Corporation is one of the largest publicly traded uranium companies in the world, headquartered in Saskatoon, Saskatchewan, Canada. Founded in 1988, Cameco is primarily involved in the exploration, mining, and production of uranium, which is a key component used in nuclear power generation. The company operates several uranium mines and projects, primarily in Canada and the United States, and it also has interests in nuclear fuel manufacturing.
