ALPHA-AMYLASE FROM ALTEROMONAS HALOPLANCTIS
OverviewOverview
Background:. Enzymes from psychrophilic (cold-adapted) microorganisms, operate at temperatures close to 0 degreesC, where the activity of their, mesophilic and thermophilic counterparts is drastically reduced. It has, generally been assumed that thermophily is associated with rigid proteins, whereas psychrophilic enzymes have a tendency to be more flexible., Results:. Insights into the cold adaptation of proteins are gained on the, basis of a psychrophilic protein's molecular structure. To this end, we, have determined the structure of the recombinant form of a psychrophilic, alpha-amylase from Alteromonas haloplanctis at 2.4 A resolution. We have, compared this with the structure of the wild-type enzyme, recently solved, at 2.0 A resolution, and with available structures of their ... [(full description)]
