Comments	P.306 right column bottom paragraph: "The pdu operon encodes seven shell proteins (PduA, -B, -J, -K, -N, -T, and -U) and one variant (PduB′), which all display similarity to the BMC (bacterial microcompartment) shell proteins of the carboxysome. Thus, in total, eight proteins appear to be associated with the shell of the propanediol utilization microcompartment. The phylogenetic relationship between the different proteins is shown in Figure 1. Most of the shell proteins have a molecular mass of 9–14 kDa, but a number (PduB, PduB′, and PduT) are more than twice this size and appear to have arisen by gene duplication and fusion, since they contain a tandem repeat of the BMC motif."
