Abstract

This study investigated the mechanism of arsenic resistance in the diazotrophic bacterium Herbaspirillum sp. GW103 isolated from rhizosphere soil of Phragmites austrails. The isolate Herbaspirillum sp. GW103 exhibited maximum tolerance to arsenic (550 mg/L). Four different arsenate reductase (arsC) genes (arsC1, arsC2, arsC3 and arsC4) were located in the genome of the isolate Herbaspirillum sp. GW103. The expression pattern of the arsC1 differed from other genes. All four types of arsC genes had different protein secondary structures and stereochemical properties. Molecular modeling and structural analysis of arsC genes revealed close structural homology with arsC family proteins from Escherichia coli (PDB ID: 1I9D) and Pseudomonas aeruginosa (PDB ID: 1RW1).
