Bacterial microcompartment shell protein PduU

UniProtKB accession:  P0A1D1

Grouped By:  Matching UniProtKB accession

UniProtKB description:  A minor shell protein of the bacterial microcompartment (BMC) dedicated to 1,2-propanediol (1,2-PD) degradation. The isolated BMC shell component protein ratio for J:A:B':B:K:T:U is approximately 15:10:7:6:1:1:2 (PubMed:12923081). Not required for structural integrity of BMCs nor to mitigate propionaldehyde toxicity, may selectively transport specific metabolites (PubMed:21239588). Proteins such as this one with circularly permuted BMC domains may play a key role in conferring heterogeneity and flexibility in this BMC (Probable).
