11 Identification of the substrate and pseudosubstrate binding sites of phosphorylase kinase gamma-subunit.Using site-directed mutagenesis, we proposed that an autoinhibitory domain(s) is located at the C-terminal region (301-386) of the phosphorylase kinase gamma-subunit (Huang, C.-Y.F., Yuan C.-J., Livanova, N.B., and Graves, D.J. (1993) Mol. Cell. Biochem. 127/128, 7-18). Removal of the putative inhib...Mutagenesis; Autoinhibitory Domain; Peptides1995-03-31
12 Effects of deletions in the central helix of calmodulin on enzyme activation and peptide binding.Using site-directed mutagenesis we have expressed in Escherichia coli three engineered calmodulins (CaM) containing deletions in the solvent-exposed region of the central helix.
