Abstract
The nucleotide sequence of the agrA gene encoding an extracellular beta-agarase of Pseudomonas atlantica was determined. An open reading frame of 1,515 nucleotides which corresponded to agrA was found. The nucleotide sequence predicts a primary translation product of 504 amino acids and Mr 57,486. Comparison of the deduced amino acid sequences of beta-agarase from P. atlantica and the extracellular beta-agarase from Streptomyces coelicolor A3(2) suggests that these proteins share several domains in common.
摘要
测定了编码大西洋假单胞菌胞外β-琼脂酶的agrA基因的核苷酸序列。发现了一个与agrA相对应的1515个核苷酸的开放阅读框。核苷酸序列预测了一个由504个氨基酸组成、分子量为57486的初级翻译产物。对大西洋假单胞菌β-琼脂酶和天蓝色链霉菌A3(2)胞外β-琼脂酶推导的氨基酸序列进行比较表明，这些蛋白质有几个共同的结构域。
