Fig. 5From: Analysis of glucose-6-phosphate dehydrogenase of the cyanobacterium Synechococcus sp. PCC 7942 in the zwf mutant Escherichia coli DF214 cellsEffect of 50 mM DTT on G6PDH activity in the pAY162 transformant E. coli DF214 cells. A 10,000 × g supernatant is used as enzyme solution. No DTT exposed supernatant was used as the positive control. For the other supernatants, 50 mM DTT was added for 5, 10 and 30 mins before activity measurements. Specific activities were given as mean of three independent measurementsBack to article page
