The enterocin CRL35 biosynthetic gene cluster was cloned and sequenced. The sequence was revealed to be highly identical to that of the mundticin KS gene cluster (S. Kawamoto, J. Shima, R. Sato, T. Eguchi, S. Ohmomo, J. Shibato, N. Horikoshi, K. Takeshita, and T. Sameshima, Appl. Environ. Microbiol. 68:3830-3840, 2002). Short synthetic peptides were designed based on the bacteriocin sequence and were evaluated in antimicrobial competitive assays. The peptide KYYGNGVSCNKKGCS produced an enhancement of enterocin CRL35 antimicrobial activity in a buffer system.
克隆并测序了肠球菌素CRL35生物合成基因簇。结果显示该序列与蒙地菌素KS基因簇的序列高度同源(S. 川本、J. 岛、R. 佐藤、T. 江口、S. 大藻藻、J. 柴幡、N. 堀越、K. 竹下和T. ameshima,《应用与环境微生物学》68:3830 - 3840,2002年)。基于该细菌素序列设计了短合成肽,并在抗菌竞争试验中进行了评估。肽KYYGNGVSCNKKGCS在缓冲系统中增强了肠球菌素CRL35的抗菌活性。
