FIG. 4.

Indels that distinguish Acinetobacter MutS homologs from those of other gram-negative bacteria. Portions of a multiple sequence alignment depicting Acinetobacter MutS indels relative to other gram-negative homologs. Dashes indicate gaps in the aligned sequences. Numerals indicate positions corresponding to amino acids in the E. coli MutS primary sequence (29) that are located immediately prior to the start of the indel. Bold type indicates amino acids that are identical to those in Acinetobacter sp. strain ADP1.
