Abstract

Proteins interacting with the biological information molecules DNA and RNA play important cellular roles in all organisms. One widespread super family of proteins implicated in such function(s) is cold shock protein (CSP) that contains the cold shock domain (CSD). This work is planned to study the three-dimensional structure, conserved residues, and different active sites in the structure of cold resistant protein (CRP) from CRPF1, cold tolerant mutant of Pseudomonas fluorescence by comparative homology modeling. Here we tried to identify crucial residues that are involved in active sites or functional sites of the protein. The study reveals that CRP represent the prototype of the CSD and share a highly similar overall fold consisting of five antiparallel b-sheets forming a b-barrel structure with surface exposed aromatic and basic residues that were responsible for nucleic acid binding properties of variable binding affinities and sequence selectivity and harbors the nucleic acid binding motifs RNP1 and RNP2 that is highly conserved in CSP family.
