microrganismo transgênico, e, processo para produzir um nucleosìdeo de purina por fermentação. |
摘要 |
A microorganism which has a gene encoding an enzyme in which feedback inhibition is desensitized by substitution of one or two amino acids in PRPP amidotransferase encoded by purF of Escherichia coli, a gene encoding a protein which is an inactivated repressor of purine nucleotide biosynthesis encoded by purR, a gene encoding an enzyme which is inactivated purine nucleoside phosphorylase encoded by deoD, a gene encoding an enzyme which is inactivated succinyl-AMP synthase encoded by purA, a gene encoding an enzyme which is inactivated 6-phosphogluconate dehydrase encoded by edd, a gene encoding an enzyme which is inactivated phosphoglucose isomerase encoded by pgi and like is bred and a purine nucleoside is produced by culturing the microorganism. |
