Abstract
- Adenylate kinase purified from Mycobacterium marinum shares homology with the enzyme from mammalian muscle and from other bacteria with respect to amino acid composition, total residues and Mr. 2. However, it differs from others in not containing a free sulfhydryl or disulfide group. 3. It is much more sensitive to inhibition by adenosine (5')pentaphospho(5')adenosine than is the enzyme from other sources. 4. The enzyme contains 24% alpha-helix, 30% beta-structure and 46% random coil.
摘要
- 从海分枝杆菌中纯化得到的腺苷酸激酶在氨基酸组成、总残基数和相对分子质量方面与哺乳动物肌肉及其他细菌中的该酶具有同源性。2. 然而，它与其他酶的不同之处在于不含有游离巯基或二硫键。3. 与其他来源的酶相比，它对腺苷(5')五磷酸(5')腺苷的抑制作用更为敏感。4. 该酶含有24%的α-螺旋、30%的β-结构和46%的无规卷曲。
