Abstract
The gene for N-carbamyl-L-amino acid amidohydrolase was cloned from Bacillus stearothermophilus strain NS1122A into E. coli. This gene started with a TTG triplet and was predicted to encode a peptide of 409 amino acids, with a calculated molecular weight of 44,248. The deduced amino acid sequence shared moderate homology with that of the corresponding enzyme of Pseudomonas sp. strain NS671.
摘要
N-氨甲酰-L-氨基酸酰胺水解酶基因从嗜热脂肪芽孢杆菌NS1122A菌株克隆到大肠杆菌中。该基因起始于TTG三联体，预计编码一个由409个氨基酸组成的肽段，计算分子量为44,248。推导的氨基酸序列与假单胞菌属NS671菌株相应酶的氨基酸序列具有中等同源性。
