Nature372(6505),432–438(1994), DOI10.1038/372432a0. Indexed primary title and byline C.Oubridge, N.Ito, P.R.Evans, C.H.Teo, K.Nagai verify a1.92angstrom RNA-binding-domain/RNA-hairpin crystal structure. Title preserves published A spelling for angstrom. The source heading retains the abbreviated first-author byline. Publisher endpoint www.nature.com/articles/372432a0 was inaccessible; no unverified atom-contact or kinetic constants attributed to it. Existing2009 U1-core paper independently supplies U1A placement at U1 stem-loopII and the distinction between core crystallization and a complete-particle model.
The indexed original publisher record explicitly identifies the first author as Chris Oubridge. Its abstract specifies a21-nucleotide RNA hairpin,ten-nucleotide loop and1.92Å structure,including loop contacts at the protein beta-sheet surface. The primary indexed byline and named MRC obituary now establish the fuller identity; direct publisher open still redirects to an inaccessible identity endpoint. www.nature.com/articles/372432a0
