FIG. 3.

Sequence alignment of the αI2 helix and the β-4,5 strand region of some integron integrases. IntI2*, class 2 integron integrase from Tn7; SamIntIA, integron integrase from S. amazonensis SB2BT (sequence framed); SonIntIA, integron integrase from S. oneidensis MR1; VchIntIA, integron integrase from the V. cholerae chromosomal integron; IntI1, class 1 integron integrase from plasmid pVS1; IntI3, class 3 integron integrase from a S. marcescens plasmid. Mutagenesis experiments were done with the S205, V206, N210, E214, P215, C227, P228, and C236 residues (identified by arrows). The coordinates of the residues in this figure are those of the SamIntIA integrase.
