enterohepatic helicobacter species | most of the members of the genus helicobacter do not normally colonize the gastric mucosa, but instead thrive in the mucosal surfaces of the intestinal tract and/or the liver of humans, other mammals, and birds. these enterohepatic helicobacter species have features of ultrastructure and physiology in common with helicobacter pylori and the other gastric helicobacter species, and have been the subject of several recent ... | 2001 | 21290746 |
analysis of five tylosin biosynthetic genes from the tyllba region of the streptomyces fradiae genome. | the tyllba region of the tylosin biosynthetic gene cluster of streptomyces fradiae contains at least five open reading frames (orfs). orf1 (tyli) encodes a cytochrome p450 and mutations in this gene affect macrolide ring hydroxylation. the product of orf2 (tylb) belongs to a widespread family of proteins whose functions are speculative, although tylb mutants are defective in the biosynthesis or addition of mycaminose during tylosin production. orfs 3 and 4 (tyla1 and tyla2) encode delta tdp-gluc ... | 1994 | 7984112 |
