[https://www.uniprot.org/uniprot/PDUJ_SALTY PDUJ_SALTY] One of the major shell proteins 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). At least one of PduA or PduJ is required for BMC assembly; it must be encoded as the first gene in the pdu operon (PubMed:33227310, PubMed:27561553). Required for structural integrity of BMCs and to mitigate propionaldehyde toxicity, probably joins facets responsible for BMC closure (PubMed:21239588). Edge residues (particularly Lys-25) are important for function and assembly of the BMC (PubMed:24747050). 80% identical to PduA; although their pore regions appear structurally identical, unlike PduA plays no role in 1,2-PD diffusion into or out of the BMC shell. If pduJ is cloned in the chromosomal position of pduA it is able to complement a pduA deletion; it then has a functional pore as it assumes the transport functions of PduA (PubMed:27561553). Overexpression of this protein leads to aberrant filaments that extend the length of the cell, cross the cleavage furrow and impair division. The filaments form nanotubes with a hollow center (PubMed:33227310). Modeling suggests PduJ is probably the hub for binding multiple enzymes to the interior of the BMC; modeling suggests PduC, PduD, PduG and PduM are targeted to PduJ (Probable).<ref>PMID:12923081</ref> <ref>PMID:21239588</ref> <ref>PMID:24747050</ref> <ref>PMID:27561553</ref> <ref>PMID:33227310</ref> <ref>PMID:25646976</ref> The 1,2-propanediol (1,2-PD) degradation 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.<ref>PMID:18296526</ref> <ref>PMID:28475631</ref> | |||
