Homologous Superfamily

RNA 3'-terminal phosphate cyclase/enolpyruvate transferase, alpha/beta (IPR013792)

Short name: RNA3'P_cycl/enolpyr_Trfase_a/b

Description

This superfamily represents an alpha/beta domain consisting of alternating beta-strands and alpha helices in two layer. This domain is found in RNA 3'-terminal phosphate cyclase (RPTC), where it occurs as a duplication of three repeats of this fold packed together around a pseudo three-fold axis [PMID: 10673421]. RNA cyclases are a family of RNA-modifying enzymes that catalyse the ATP-dependent conversion of the 3'-phosphate to the 2',3'-cyclic phosphodiester at the end of RNA. These cyclases contain an insert alpha/beta domain with a thioredoxin topology (IPR013791).

This domain is also found in enolpyruvate transferase, where it occurs as a duplication of six repeats of this fold organised into two RPTC-like domains [PMID: 9485407, PMID: 15995357]. Enolpyruvate transferase is the first enzyme in bacterial peptidoglycan biosynthesis, catalysing the transfer of enolpyruvate from phosphoenolpyruvate to UDP-N-acetyl-glucosamine.
