Acetate kinase EutQ

UniProtKB accession:  Q9ZFV5

Grouped By:  Matching UniProtKB accession

UniProtKB description:  A bidirectional acetate kinase that may drive flux through the ethanolamine (EA) degradation pathway under anoxic conditions found when this bacteria infects the host intestine. It may generate ATP that can be used by other enzymes (EutA and EutT) in the eut pathway. Can use GTP instead of ATP with reduced efficiency (PubMed:26448059). Might be required to correctly target EutE to bacterial microcompartments (BMC) (Probable). Required for the biogenesis of multiple mobile BMCs per cell. Might serve as an assembly hub for BMC shell proteins. Expression of eutK, eutL, eutM, eutN, eutS (eutSMNLK) in E.coli leads to formation of a single BMC; coexpression of eutQ with eutSMNLK permits E.coli to make cells with more than one mobile BMC, as is usual in vivo. EutS alone also forms BMCs, but in the presence of eutQ both BMCs and protein filaments are formed (PubMed:27063436).
