An allosteric transcription regulator called HisP regulates the enzymes for histidine biosynthesis in thebactrium Ecolis histidine modulates HisP activity, on binding histidine , HisP alters its conformation, markedly changing its affinityfor the regulatory sequences in the promoters of the genes for the histidine biosynthetic enzymes.A if His P function as a gne repressor ,would you expect that his P would bind more tigthly or less tigthly to the regulatory esquence when histidine is abundant? explain your answerB if His P fucnction as a gene activator, would you expect that HisP would bind more tightly or less tightly to the regulatory sequences when histidine levels are low ? expalin your answer
