ECMDB

Identification

Name:

5'-nucleotidase yjjG

Synonyms:

Nucleoside 5'-monophosphate phosphohydrolase

Gene Name:

yjjG

Enzyme Class:

3.1.3.5

Biological Properties

General Function:

Involved in catalytic activity

Specific Function:

Nucleotidase that shows high phosphatase activity toward three nucleoside 5'-monophosphates, UMP, dUMP, and dTMP, and very low activity against TDP, IMP, UDP, GMP, dGMP, AMP, dAMP, and 6- phosphogluconate. Is strictly specific to substrates with 5'- phosphates and shows no activity against nucleoside 2'- or 3'- monophosphates. Might be involved in the pyrimidine nucleotide substrate cycles
