NUCLEOSIDE DIPHOSPHATE KINASE ISOFORM A FROM BOVINE RETINA
|
Overview
The crystal structures of two isoforms of nucleoside diphosphate kinase, from bovine retina overexpressed in Escherischia coli have been determined, to 2.4 A resolution. Both the isoforms, NBR-A and NBR-B, are hexameric and, the fold of the monomer is in agreement with NDP-kinase structures from, other biological sources. Although the polypeptide chains of the two, isoforms differ by only two residues, they crystallize in different space, groups. NBR-A crystallizes in space group P212121 with an entire hexamer, in the asymmetric unit, while NBR-B crystallizes in space group P43212, with a trimer in the asymmetric unit. The highly conserved, nucleotide-binding site observed in other nucleoside diphosphate kinase, structures is also observed here. Both NBR-A and NBR-B were crystallized, in ... [(full description)]
