2.3.3.14 | H72L |
replacement of His72 by leucine makes HCS resistant to lysine inhibition, demonstrating the regulatory role of this conserved residue |

activity and protein level of homocitrate synthase are dramatically reduced upon depletion of CuZn-superoxide dismutase. Overexpression of the lys4 gene increases homocitrate synthase activity and is sufficient to suppress the lysine requirement of CuZn-superoxide dismutase-deficient cells |

the RAM domain is responsible for enzyme inhibition. A mutant enzyme lacking the RAM domain is insensitive to inhibition by lysine |
