1966Nature 23 July 383/2 Ribosomes may contain enzyme systems capable of transferring a peptidyl-sRNA from the amino-acid site to the peptide site. 1971D. J. Cove Genetics ix. 131 One site, the peptidyl site will bind a peptidyl-sRNA complex and the other, the amino-acyl site will bind an amino-acyl-sRNA complex. 1977Lancet 19 Mar. 628/2 These may then form cross-links via spontaneous Schiff-base formation with the ε-amino group of a nearby peptidyl lysine or hydroxylysine, or via the aldol condensation of two such aldehydes. 1979Nature 4 Jan. 66/2 Active ribosomes were quantified by allowing the nascent peptidyl chains of active ribosomes to complete polypeptide synthesis in the presence of the initiation inhibitor, pactamycin. 1988EMBO Jrnl. VII. 3949/1 Antibiotics known to inhibit peptidyl transferase activity had a pronounced effect on photo-crosslinking. |
