Phosphate propanoyltransferase

UniProtKB accession:  Q21A54

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Involved in 1,2-propanediol (1,2-PD) utilization within the bacterial microcompartment (BMC) dedicated to 1,2-PD degradation by catalyzing the conversion of propanoyl-CoA to propanoyl-phosphate. CoA is regenerated within the pdu BMC (for use by PduP) via this enzyme, although there must also be cofactor transport across the BMC (PubMed:26959993). Directly targeted to the BMC (By similarity). Phosphate is probably the first substrate to bind in the forward direction. CoA is probably the first substrate to bind in the reverse direction, and might bind to the enzyme as the BMC assembles, ensuring cofactor encapsulation (Probable).
