Escherichia coli K-12 substr. MG1655 Enzyme: sugar phosphatase

Gene: yidA Accession Numbers: EG11195 (EcoCyc), b3697, ECK3689

Regulation Summary Diagram: ?

YidA is a promiscuous sugar phosphatase belonging to the superfamily of haloacid dehalogenase (HAD)-like hydrolases. Its preferred substrate is erythrose-4-phosphate [Kuznetsova06]. YidA selectively hydrolyzes α-D-glucose-1-phosphate and has no activity with the β form [Kuznetsova06]. The phosphatase activity of YidA was first discovered in a high-throughput screen of purified proteins [Kuznetsova05].

Mutagenesis of the predicted catalytic Asp residues in YidA results in loss of phosphatase activity [Kuznetsova06].
