Escherichia coli K-12 substr. MG1655 Polypeptide: predicted truncated N-acetylgalactosamine-6-phosphate deacetylase

Gene: agaA Accession Numbers: EG12766 (EcoCyc), b3135, ECK3123

Synonyms: yraA

Regulation Summary Diagram: ?

Regulation summary diagram for agaA

Though AgaA is predicted to be an N-acetylgalactosamine-6-phosphate deacetylase, it also appears to be nonfunctional by dint of having an amino-terminal deletion [Reizer96, Homma02].
