... l-gulono-1,4-lactone dehydrogenase of M. tuberculosis is a specific enzyme for the biosynthesis of L-AA. As far as we know, this is the first report of a specific biosynthetic enzyme for vitamin C in bacteria. To ... characterized up to now, and the first example of a specific, vitamin C biosynthetic enzyme of bacterial origin. Further studies will be necessary to elucidate th...

... sets for specificity (Fig. 1). Results showed that primer set of 3' NTR had good results but the primer sets of prM and 5' NTR didn’t. Therefore, primers and probe of 3' NTR for the ... added to RT-mix for synthesis of cDNA. The RT-mix consisted of 6 µ l of 5X Universal buffer, 3 µ l of 0.1 µ l M DDT, 1 µ l of 10 mM dNTP, 1 µ l of reverse primer (2...
