Mammalian phosphorylase isozymes from muscle, brain and liver were expressed in Escherichia coli and purified from the crude bacterial cell extracts in one step using a copper-loaded, metal-affinity matrix. Good chromatographic behavior, enzyme activ

Immobilized metal-chelate affinity chromatography has been widely used in the purification of proteins, and we have recently found that it can also be applied to purification of nucleic acids through interactions involving exposed bases, especially p

The X-ray crystal structure of the copper complex of the rat trypsin mutant Arg96 to His96 (trypsin R96H) has been determined in order to ascertain the nature of the engineered metal-binding site and to understand the structural basis for the metal-i

Proteins can make use of metal ions to bind substrates, to maintain structure, to effect catalysis, and for allosteric control and regulation. In order to hold a particular metal ion with high affinity and specificity, proteins form multidentate bind
Characterization of His-X3-His sites in alpha-helices of synthetic metal-binding bovine somatotropin

Variants of bovine somatotropin have been engineered to contain synthetic metal-binding sites consisting of two solvent-exposed histidines separated by a single turn of an alpha-helix (His-X3-His variants). The affinities of these proteins for Cu(II)

A metal-binding site consisting of two histidines positioned His-X3-His in an alpha-helix has been engineered into the surface of Saccharomyces cerevisiae iso-1-cytochrome c. The synthetic metal-binding cytochrome c retains its biological activity in

A recombinant trypsin was designed whose catalytic activity can be regulated by varying the concentration of Cu2+ in solution. Substitution of Arg-96 with a His in rat trypsin (trypsin R96H) places a new imidazole group on the surface of the enzyme n

Ruthenium and osmium hydridonitrosyl complexes, [MH(NO)(PPh3)3], react with perfluorocarboxylic acids RCO2H (R = CF3 or C2F5) to afford the products [Ru(O2CR)3(NO)(PPh3)2] and [OsH(O2CR)2(NO)(PPh3)2] respectively. The reaction intermediates [RuH(O2CR

Aryldiazo complexes, [M(CO)$sub 2$(NNPh)(PPh$sub 3$)$sub 2$][PF$sub 6$](M = Os, Ru; Ph = C$sub 6$H$sub 5$), were prepared by allowing diazonium salts to react with M(CO)$sub 3$(PPh$sub 3$)$sub 2$. Infrared spectra of the Ru complex suggest the presen
