Ribonuclease alpha-sarcin

UniProtKB accession:  P00655

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Alpha-sarcin is specific for purines in both single- and double-stranded RNA. Its toxic action on eukaryotic cells is the result of cleavage of a single phosphodiester bond in the 60S subunit of ribosomes (By similarity). Inhibits both the EFl (elongation factor 1)-dependent binding of aminoacyl-tRNA and the GTP-dependent binding of EF2 (elongation factor 2) to ribosomes (PubMed:2930482).
