(A) Predicted Mbb1 protein sequence. S, V, R, and A residues are marked in bold in the putative transit peptide. Consensus residues V and A of the potential cleavage site are underlined. The 10 aligned TPR domains are shown on top of each other together with the Mbb1 consensus and the general TPR consensus. The domains A and B are indicated by lines above the TPRs (see Discussion). Residues present at least five times among the 10 TPRs of Mbb1 are framed, and similar amino acids are circled. Identical and similar residues in Mbb1 and the Arabidopsis protein BAA9482 are shaded. (B) Alignment of the Mbb1 and Arabidopsis BAA9482 protein sequences.
