The gua operon is responsible for regulating the synthesis of guanosine mono phosphate(GMP), a purine nucleotide, from inosine monophosphate (IMP or inosinate). It consists of two structural genes guaB(encodes for IMP dehydrogenase or IMPDH) and guaA(encodes for GMP synthetase) apart from the promoter and operator region.
