Abstract:
:The gcaD, prs, and ctc genes were shown to be organized as a tricistronic operon. The transcription of the prs gene, measured as phosphoribosyl diphosphate synthetase activity, and of the ctc gene, measured as beta-galactosidase activity specified by a ctc-lacZ protein fusion, were dependent on the promoter in front of the gcaD gene. Analysis of cDNA molecules prepared with gcaD-prs-ctc-specified mRNA as the template revealed an RNA transcript that encompassed all three cistrons.

杂志文章abstract::Mevalonate (MVA) metabolism provides the isoprenoids used in archaeal lipid biosynthesis. In synthesis of isopentenyl diphosphate, the classical MVA pathway involves decarboxylation of mevalonate diphosphate, while an alternate pathway has been proposed to involve decarboxylation of mevalonate monophosphate. To identi...
