CC -!- FUNCTION: Involved in 1,2-propanediol (1,2-PD) utilization within the
CC bacterial microcompartment (BMC) dedicated to 1,2-PD degradation by
CC catalyzing the conversion of propanoyl-CoA to propanoyl-phosphate.
CC Required for optimal growth on 1,2-PD. CoA is regenerated within the
CC BMC (for use by PduP) via this enzyme, although there must also be
CC cofactor transport across the BMC. Directly targeted to the BMC.
CC {ECO:0000250|UniProtKB:Q9XDN5}.
CC -!- FUNCTION: Expression of a cosmid containing the full 21-gene pdu operon
CC in E.coli allows E.coli to grow on 1,2-propanediol (1,2-PD) with the
CC appearance of bacterial microcompartments (BMC) in its cytoplasm.
CC {ECO:0000269|PubMed:18332146}.
CC -!- FUNCTION: The 1,2-PD-specific bacterial microcompartment (BMC)
CC concentrates low levels of 1,2-PD catabolic enzymes, concentrates
CC volatile reaction intermediates thus enhancing pathway flux and keeps
CC the level of toxic, mutagenic propionaldehyde low. {ECO:0000305}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=phosphate + propanoyl-CoA = CoA + propanoyl phosphate;
CC Xref=Rhea:RHEA:28046, ChEBI:CHEBI:43474, ChEBI:CHEBI:57287,
CC ChEBI:CHEBI:57392, ChEBI:CHEBI:58933; EC=2.3.1.222;
CC Evidence={ECO:0000250|UniProtKB:Q9XDN5};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000250|UniProtKB:Q21A54};
CC Note=There are 2 Zn(2+) ions per monomer; Zn(2+) and CoA bind inbetween
CC the 2 domains in each monomer. {ECO:0000250|UniProtKB:Q21A54};
CC -!- PATHWAY: Polyol metabolism; 1,2-propanediol degradation.
CC {ECO:0000269|PubMed:18332146}.
CC -!- SUBCELLULAR LOCATION: Bacterial microcompartment
CC {ECO:0000250|UniProtKB:Q9XDN5}.
CC -!- DOMAIN: Formed by 2 beta-barrels, each is capped on both ends by short
CC alpha-helices. {ECO:0000250|UniProtKB:Q21A54}.
CC -!- SIMILARITY: Belongs to the PduL family. {ECO:0000305}.
