'''LIPASE II FROM RHIZOPUS NIVEUS'''<br />


==Overview==
==LIPASE II FROM RHIZOPUS NIVEUS==
The crystal and molecular structure of Lipase II from Rhizopus niveus was, analyzed using X-ray single crystal diffraction data at a resolution of, 2.2 A. The structure was refined to an R-factor of 0.19 for all available, data. This lipase was purified and crystallized as Lipase I, which, contains two polypeptide chains combined through non-covalent interaction., However, during crystal growth, Lipase I was converted to Lipase II, which, consists of a single polypeptide chain of 269 amino acid residues, by, limited proteolysis. The structure of Lipase II shows a typical alpha/beta, hydrolase fold containing the so-called nucleophilic elbow. The catalytic, center of this enzyme is analogous to those of other neutral lipases and, serine proteases. This catalytic center is sheltered by an ...

== Publication Abstract from PubMed ==
The crystal and molecular structure of Lipase II from Rhizopus niveus was analyzed using X-ray single crystal diffraction data at a resolution of 2.2 A. The structure was refined to an R-factor of 0.19 for all available data. This lipase was purified and crystallized as Lipase I, which contains two polypeptide chains combined through non-covalent interaction. However, during crystal growth, Lipase I was converted to Lipase II, which consists of a single polypeptide chain of 269 amino acid residues, by limited proteolysis. The structure of Lipase II shows a typical alpha/beta hydrolase fold containing the so-called nucleophilic elbow. The catalytic center of this enzyme is analogous to those of other neutral lipases and serine proteases. This catalytic center is sheltered by an alpha-helix lid, which appears in neutral lipases, opening the active site at the oil-water interface.
