Abstract
By using [3H]mannobiose as a labelled acceptor, it was possible to demonstrate transfer reactions catalysed by two beta-mannanases, with mannotetraose and mannopentaose as substrates. The enzyme from Streptomyces transfers one mannose unit from the oligosaccharides, whereas the enzyme from fenugreek (Trigonella foenum-graecum) seeds is able to transfer oligomannose residues.
摘要
通过使用[3H]甘露二糖作为标记受体，得以证明两种β-甘露聚糖酶催化的转移反应，其底物分别为甘露四糖和甘露五糖。链霉菌来源的酶从寡糖上转移一个甘露糖单元，而胡芦巴（Trigonella foenum-graecum）种子来源的酶能够转移低聚甘露糖残基。
