Involved in 1,2-propanediol (1,2-PD) utilization in the bacterial microcompartment (BMC) dedicated to 1,2-PD degradation by catalyzing the conversion of propanoyl-CoA to propanoyl-phosphate. Also able to catalyze the reverse reaction. Also has phosphate acetyltransferase activity to a lesser extent (PubMed:17158662). Required for optimal growth on 1,2-PD when the BMC is intact. CoA is regenerated within the BMC (for use by PduP) via this enzyme, although there must also be cofactor transport across the BMC. Directly targeted to the BMC (PubMed:25962918). The 1,2-PD-specific bacterial microcompartment (BMC) concentrates low levels of 1,2-PD catabolic enzymes, concentrates volatile reaction intermediates thus enhancing pathway flux and keeps the level of toxic, mutagenic propionaldehyde low. phosphate + propanoyl-CoA = CoA + propanoyl phosphate There are 2 Zn(2+) ions per monomer; Zn(2+) and CoA bind inbetween the 2 domains in each monomer. The above values were measured with a recombinant PduL fused to eight C-terminal histidine residues (PduL-His8). The Vmax values may be underestimated due to the instability of PduL-His8. Polyol metabolism; 1,2-propanediol degradation. Monomer, when purified in the absence of the encapsulation peptide (EP, residues 1-27). The EP may influence oligomerization. Probably located inside the BMC shell. BMC production is induced by growth on 1,2-PD vitamin B12 medium. The N-terminal 20 residues target foreign proteins (tested with eGFP) to the BMC (PubMed:25962918). Formed by 2 beta-barrels, each is capped on both ends by short alpha-helices (By similarity). Unable to ferment 1,2-PD, impaired for aerobic growth on this compound. Evolutionarily distinct from Pta (phosphate acetyltransferase). Bacterial microcompartments (BMC) 100-200 nm in cross section are formed during aerobic growth on minimal 1,2-PD-B12 or anaerobic growth on 1,2-PD-tetrathionate medium, but not during aerobic growth on glucose, anerobic growth on glucose or pyruvate-tetrathionate (PubMed:10498708). BMCs can constitute up to 10% of total cell protein (PubMed:12923081). Belongs to the PduL family.
