Notes

[back to top]


Nudix hydrolase. RppH removes 5' triphosphate from primary transcripts, enhancing RNase E activity (Deana, 2008). Required for invasion of cultured mammalian cells by both E. coli K1 and S. typhimurium. NudH also hydrolyzes Ap5A and Ap4A. Ribosome-associated protein (Jiang, 2007).[5]
