abstract：:Hepatic cysteine sulfinic acid decarboxylase (EC 4.1.1.29) activity has been reported to decrease in response to both L-methionine (Met) feeding and adrenalectomy in rats. A series of experiments was conducted to (a) determine if CSAD depression was evident in female rats fed a methionine-supplemented diet; and (b) de...

abstract：:The tertiary structure model of EF-Tu predicts that the amino acid sequence Val-Asp-His-Gly-Lys-Thr-Thr-Leu (residues 20-27) forms a pocket that binds the pyrophosphate group. To test this model we used site-directed mutagenesis to produce forms of EF-Tu altered in this region. The following mutations were constructed...
