FIG. 3.

(A) Alignment of the N-terminal three repeats found in EngE. (B) Alignment of the sequences shown in panel A with similar sequences of HLDs of C. cellulovorans (C.v) CbpA, C. cellulolyticum (C.c) CipC, Clostridium josui (C.j) CipA, and Clostridium stercorarium (C.s) AviII and EngZ. Amino acid residues identical or similar to those in the consensus region are shown as white letters on a black background. Similar amino acids are as follows: F, I, V, L, and M; R and K; S and T; D and E; N and Q; and F, Y, and W. Gaps left to improve alignment are indicated by dashes. The numbers refer to amino acid residues at the start and end of the respective lines; all sequences are numbered from Met-1 of the peptide.
