Bacterial Adaptor Membrane Fusion Proteins and the Structurally Dissimilar Outer Membrane Auxiliary Proteins Have Exchanged Central Domains in 𝛼-Proteobacteria

Figure 2

A second alignment, comparable to that shown in Figure 1 using two different proteins that showed similar degrees of similarity throughout the lengths of their α-helical regions. The OMA homologue was from Sinorhizobium meliloti (top; NP_437192) while the MPF was from another α-proteobacterium, Rhodospirillum centenum (bottom; YP_002296615). The alignment and comparison scores were determined as for Figure 1 giving 32% identity, 45% similarity, 2 gaps, and a comparison score of 23 S.D.
