The environment of Trp57, introduced by the mutation of a tyrosine in the dynamic loop of porcine liver fructose-1,6-bisphosphatase (FBPase), was examined using time-resolved fluorescence and directed mutation. The Trp57 enzyme was studied previously

Hexokinase I, the pacemaker of glycolysis in brain tissue, is composed of two structurally similar halves connected by an alpha-helix. The enzyme dimerizes at elevated protein concentrations in solution and in crystal structures; however, almost all

By exerting strategic control on purine nucleotide biosynthesis, and by engaging GTP-dependent transphosphorylation of IMP to activate loss of an oxygen atom during catalysis, adenylosuccinate synthetase remains as enzyme that justifiably fascinates

Hexokinase I, the pacemaker of glycolysis in brain tissue and red blood cells, is comprised of two similar domains fused into a single polypeptide chain. The C-terminal half of hexokinase I is catalytically active, whereas the N-terminal half is nece

On the basis of ligated crystal structures, Asn21, Asn38, Thr42, and Arg419 are not involved in the chemical mechanism of adenylosuccinate synthetase from Escherichia coli, yet these residues are well conserved across species. Purified mutants (Asp21

Mutations Ser119-->Glu, Ser119-->Gly, Ser119-->Trp, Gly121-->Ala and Gly121-->Ala/Ser411-->Gly were constructed in glucoamylase to change substrate specificity. Mutation Ser411-->Gly was already known to decrease glucoamylase selectivity toward isoma

(+)-Hydantocidin, a recently discovered natural spironucleoside with potent herbicidal activity, is shown to be a proherbicide that, after phosphorylation at the 5' position, inhibits adenylosuccinate synthetase, an enzyme involved in de novo purine
