 Structure and mechanism of Mycobacterium smegmatis polynucleotide phosphorylase by Mihaela-Carmen Unciuleac and others

RNA27(8),959–969(2021), DOI10.1261/rna.078822.121; PMID34088850. Primary byline verifies co-first authors Mihaela-Carmen Unciuleac and Shreya Ghosh. Abstract and cryo-EM Results identify a ring-shaped trimer, terminal RNA in an active site and an adenine base in the central tunnel. Figure4 distinguishes observed RNA/metals from an imported comparison phosphate. No complete RNA transit trajectory inferred from a static density map.
