ABSTRACT
Sequencing of the genome of
Clostridium botulinum
strain Hall A revealed a gene (CBO0515), whose putative amino acid sequence was suggestive of the rare enzyme
N
5
-(1-carboxyethyl) ornithine synthase. To test this hypothesis, CBO0515 has been cloned, and the encoded polypeptide was purified and characterized. This unusual gene appears to be confined to proteolytic strains assigned to group 1 of
C. botulinum
.
摘要
肉毒杆菌基因组测序
肉毒梭菌
霍尔A菌株的基因组测序发现了一个基因(CBO0515),其推测氨基酸序列表明这是一种罕见的酶
N
5
-(1-羧乙基) 鸟氨酸合成酶。为了验证这一假设,我们克隆了 CBO0515,并纯化和鉴定了其编码的多肽。这种不寻常的基因似乎仅限于属于肉毒杆菌第 1 组的蛋白水解菌株。
