additional information
-
binding of MgATP to an allosteric site provokes inhibition and a dimer-tetramer conversion of the enzyme, mutant generation by successive deletions of up to 10 residues and point mutations at the C-terminal end, elevated KM values for MgATP that fails to show the dimer-tetramer conversion, Y306 required for the quaternary packing involved in the dimer-tetramer conversion, the following residue L307 is crucial for the ternary packing necessary for the catalytic MgATP-binding site, dimer-tetramer conversion can be uncoupled from the conformational changes that lead to the MgATP-induced allosteric inhibition
