Importance of the loop at residues 230-245 in the allosteric interactions of Escherichia coli aspartate carbamoyltransferase.

Site-directed mutagenesis has been used to replace tyrosine-240 with phenylalanine in each of the catalytic chains of aspartate carbamoyltransferase. Tyrosine-240 is part of a loop in the structure of the enzyme, between residues 230 and 245, which undergoes a substantial conformation change as the...
