|Gene:||pseI||Accession Number: G-11090 (MetaCyc)|
Synonyms: NeuB3, Cj1317
Species: Campylobacter jejuni
The pseI of Campylobacter jejuni was discovered based on its similarity to the neuB gene, which encodes N-acetylneuraminate synthase. The gene was cloned and expressed in Escherichia coli, and the recombinant protein was purified [Chou05]. The purified enzyme catalyzed the predicted reaction in vitro, confirming its predicted activity.
Molecular Weight of Polypeptide: 38.647 kD (from nucleotide sequence), 38.67 kD (experimental) [Chou05 ]
