X-ray diffraction data using Sedoheptulose 7-phosphate isomerase (CpGmhA) from Colwellia psychrerythraeastrain 34H

The psychrophilic organism Colwellia psychrerythraea strain 34H has been demonstrated that high concentrated production of polysaccharide substrates at low temperature is a mechanism of adaptation in cold environment. The Sedoheptulose 7-phosphate isomerase(GmhA) is an essential enzyme involved the biosynthesis of polysaccharide. The crystal structure of a CpGmhA from Colwellia psychrerythraea strain 34H has been determined to up to a 2.8Ã… resolution. The CpGmhA structure reported here provides further insights into the structural correlation between activity and structure.
To investigate psychrophilic enzymes molecular basis of cold adaptation of Colwellia psychrerythraea 34H, we have cloned and over-expressed the methylmalonate-semialdehyde dehydrogenase and determined the structure by using X-ray crystallographic experiments
