EC 5.4.99.19     
Accepted name: 16S rRNA pseudouridine516 synthase
Reaction: 16S rRNA uridine516 = 16S rRNA pseudouridine516
Other name(s): 16S RNA pseudouridine516 synthase; 16S PsiI516 synthase; 16S RNA Ψ516 synthase; RNA pseudouridine synthase RsuA; RsuA; 16S RNA pseudouridine 516 synthase
Systematic name: 16S rRNA-uridine516 uracil mutase
Comments: The enzyme is specific for uridine516 in 16S rRNA. In vitro, the enzyme does not modify free 16S rRNA. The preferred substrate is a 5′-terminal fragment of 16S rRNA complexed with 30S ribosomal proteins [1].
