Previously thought to inhibit protein synthesis initiation [2]. This protein may also be involved in the regulation of purine biosynthesis [3]. Yjg ...	Endoribonuclease active on single-stranded mRNA. Inhibits protein synthesis by cleavage of mRNA [1]. Previously thought to inhibit protein synthesis initiation [2]. This protein may also be involved in the regulation of purine biosynthesis [3]. YjgF (renamed RidA) family members are enamine/imine deaminases. They hydrolyze reactive intermediates released by PLP-dependent enzymes, including threonine dehydratase [5]. YjgF also prevents inhibition of transaminase B (IlvE) in Salmonella [4].	Domain
