Multiple alignments of the deduced amino acid sequence of the heat-shock protein CplX-like gene of Azospirillum brasilense 8-I-gfp (Acc. no. AY918963) with the corresponding sequences of cplX genes from Sinorhizobium meliloti (Acc. no. NP385362), Mesorhizobium loti (Acc. no. NP108565), Bradyrhizobium japonicum (Acc. no. NP771583), and Azospirillum brasilense Sp7 (Acc. no. AAD37436). The Zn-binding motif, and the ATP-binding domains are indicated by lines and inverted arrows. Residue 292 (V), in a box, indicates the insertion point of the transposon.
