Ami 4b molecule. (A) Amino acid sequence of the ami gene product from CHUT 82337. The signal peptide is underlined, as is the short RTSXTFI sequence present in InlB (see panel C). The amidase domain (positions 1 to 261) and the CWA domain (positions 262 to 770) are indicated. The a and b modules of the three GW repeats (positions 277 to 770), designated R1a to R3a and R1b to R3b, are aligned. The repeat consensus sequence (con) shows the amino acids that are identical in at least two of three repeats. (B) Amino acid sequence of the CWA domain of Ami 1/2a (strain EGD). The a and b modules of the four GW repeats (positions 274 to 917), designated R1a to R4a and R1b to R4b, are aligned. Dashes represent gaps introduced to maximize matching (see panel C). The repeat consensus sequence (con) shows the amino acids that are identical in at least three of four repeats. Asterisks indicate identity with the repeat consensus sequence of Ami 4b. (C) Amino acid sequence of the CWA domain of InlB 1/2a (strain EGD). The a an b modules of the two GW repeats (positions 399 to 630) are designated R′1a, R′1b, R′2a, and R′2b. R′1a is missing, and R′1b is incomplete (68 amino acids). Asterisks indicate amino acids that are identical in R′2 and in the repeat consensus sequence of Ami 4b. The short RTSXTFI sequence, common to InlB and Ami 4b and absent from Ami 1/2a (see panel B), is underlined.
