Escherichia coli K-12 substr. MG1655 Polypeptide: conserved protein



Gene: yhjY Accession Numbers: EG12269 (EcoCyc), b3548, ECK3535

Regulation Summary Diagram: ?

Summary:
YhjY is predicted to be an outer membrane protein [Casadio03].

A yhjY null mutant was reported to produce less hydrogen than wild type under fermentation conditions [Mohd12]. No attempt to complement the mutant phenotype with wild-type yhjY is reported.
