Abstract
Secretion of cold-adapted alpha-amylase from Pseudoalteromonas haloplanktis TAB23 was studied in three Antarctic bacteria. We demonstrated that the enzyme is specifically secreted in the psychrophilic hosts even in the absence of a protein domain that has been previously reported to be necessary for alpha-amylase secretion in Escherichia coli. The occurrence of two different secretion pathways in different hosts is proposed.
摘要
对三种南极细菌中嗜冷嗜盐假交替单胞菌TAB23分泌冷适应α-淀粉酶的情况进行了研究。我们证明，即使在缺乏先前报道的对大肠杆菌中α-淀粉酶分泌所必需的蛋白质结构域的情况下，该酶仍能在嗜冷宿主中特异性分泌。我们提出在不同宿主中存在两种不同的分泌途径。
