Cytochrome P450nor catalyzes an unusual reaction that transfers electrons from NADP/NADPH to bound heme directly. To improve the expression level of P450nor2 from Cylindrocarpon tonkinense (C.P450nor2), Escherichia coli system was utilized to substitute the yeast system we constructed for expression of the P450nor2 gene, and the protein was purified in(More)
In order to study the structure and expression patterns of uridine diphosphate glucose dehydrogenase (UDPGH) genes in Ipomoea batatas, the transcriptome database of this plant constructed in our lab was first analyzed to screen UDPGH contigs. It was found that there were 23 UDPGH contigs of different sizes in the transcriptome database. Primers were(More)
Phytochrome A (phyA), as a photoreceptor, has a profound influence on plant growth and development and participates in many important physiological processes, such as seed germination, seeding deetiolation, and flowering. On the basis of transcriptome database of sweet potato (Ipomoea batatas (L.) Lam.), phyA gene was cloned and sequenced. The gene has an(More)
Rat was used to characterize Chinese Yam polysaccharides (CYPs). In Exp. 1, maximum volume and rate of gas production in CYP 3-supplemented group were higher than other CYP-supplemented groups and control group, while pH values and NH3 contents in CYP 2-, CYP 3-, and CYP 4-supplemented groups were lower than control group. Contents of acetate, propionate(More)
