Abstract
DmpR (dimethylphenol regulatory protein) is a member of the NtrC family of transcriptional activators and controls the transcription of the dmp operons in response to aromatic effector compounds. Secondary structure and fold recognition prediction of N-terminal A domain of this protein (210 amino acid) was performed in Genesilico Metaserver and 3DJury. The consensus result from these servers suggested MJ_1460 as a template. Three dimensional structures were generated from the sequence structure alignments of the template and target protein with MODELLER. The results suggested that the N-terminal A domain of DmpR belongs to Muramoyl pentapeptide carboxypeptidase domain family. The binding interaction sites of the known effectors were predicted using protein-ligand docking. The proposed active site of N-terminal A domain of DmpR comprises of key residues such as Phe93, Glu127, Phe132, Ser160, Phe163, Met164, Arg166 and Pro189. The findings provide some direction to the experimental studies that aim to broaden the range of phenolic derivative which can be sensed by N-DmpR in order to improve the biodegradation potential.
