Bioinformatics analysis of catB gene. a Schematic diagram of the catB gene in the genome of PXO99A. The open arrows indicate length, location and orientation of the ORFs. The middle element shows catB was amplified by PCR primers P1 and P2 and cloned into the plasmid pBBR1MCS-4 for complementation of ∆catB. The lower element shows domain structure analyses of the putative CatB protein. The lowest element shows catB was exchanged with Gm r gene in ∆catB. b Sequence alignment of CatB (PXO_02830) in Xoo PXO99A was performed by using DNAMAN software. KatA and KatE were two catalases which have been experimentally validated in Bacillus subtilis (Bs) and Xanthomonas axonopodis pv. citri (Xac), respectively. The amino acid residues highlighted with black means the homology level is 100 %, and with blue means the homology level ≥ 50 %
