The objectives of the current studies were to determine the roles of key enzymes in central carbon metabolism in the context of increased production of antibiotics in Streptomyces coelicolor. Genes for glucose-6-phosphate dehydrogenase and phosphoglucomutase (Pgm) were deleted and those for the acetyl coenzyme A carboxylase (ACCase) were overexpressed.(More)
This study focused on the involvement of the unusual nucleotide (p)ppGpp, a stringent factor, during the morphological and physiological differentiation of Streptomyces coelicolor. Two genes, relA and rshA, were disrupted to demonstrate the roles of the stringent factor in the differentiation. The intracellular concentration of (p)ppGpp in the wild-type(More)
In this study, we found that deoxyinosine triphosphate (dITP) could inhibit polymerase chain reaction (PCR) amplification of various family B-type DNA polymerases, and 0.93% dITP was spontaneously generated from deoxyadenosine triphosphate during PCR amplification. Thus, it was hypothesized that the generated dITP might have negative effect on PCR(More)
