HP_0326

Gene
HP_0326
Protein
Pseudaminic acid cytidylyltransferase and UDP-2,4-diacetamido-2,4,6-trideoxy-beta-L-altropyranose hydrolase
Organism
Helicobacter pylori (strain ATCC 700392 / 26695)
Length
517 amino acids
Function
Catalyzes the fourth and sixth steps in the biosynthesis of pseudaminic acid, a sialic-acid-like sugar that is used to modify flagellin. The C-terminus mediates the fourth step of the pathway and catalyzes the removal of UDP from C-1 of UDP-2,4-diacetamido-2,4,6-trideoxy-beta-L-altropyranose forming 2,4-diacetamido-2,4,6-trideoxy-beta-L-altropyranose. The N-terminal part mediates the last step of the pathway by mediating activation of pseudaminic acid with CMP by forming CMP-pseudaminic acid.
Similarity
In the C-terminal section; belongs to the PseG family.
