1,2-propanediol utilization protein T (PduT), Bacterial Micro-Compartment (BMC) domain repeat 2
PduT proteins are homologs of the carboxysome shell protein. They are encoded within the pdu operon and might be required for the formation of the outer shell of the bacterial pdu polyhedral organelles which are involved in coenzyme B12-dependent degradation of 1,2-propanediol. Although it has been suggested that PduT might form hexamers and further assemble into the flat facets of the polyhedral outer shell of pdu organelles, at present no experimental evidence directly supports this view. PduT proteins contain two tandem BMC domains repeats. This CD contains repeat 2 (the second BMC domain of PduT) as well as carboxysome shell protein sequence homolog, EutM protein, are also included in this CD. They too might exist as hexamers and might play similar functional roles in the construction of the eut organelle outer shell which still remains poorly understood.
