title: Structural analyses of the permease like protein SoxT: a member of the sulfur compound metabolizing sox operon.
abstract: One of the oldest known gene clusters that are involved in biological oxidation processes is the sox operon. This operon is present in different microbial species. In the present study an attempt has been made to analyze the probable structural role of SoxT protein from Pseudaminobacter salicylatoxidans. This protein has been predicted to be a permease-like protein. A comparative model of the protein has been made and analyzed. The possible membrane spanning region of the protein has been detected by structural bioinformatics approach. The inducer of the sulfur oxidation process has been predicted. And thereby the plausible mechanism of the transport of the sulfur anion inside the bacterial cell has been elucidated. Since this is the first study regarding the structural aspect of the protein this study may shed light on the theory of the yet unknown molecular mechanism of the sulfur oxidation process by sox operon.
