The endoglucanase CelB isolated from culture filtrates of Streptomyces lividans IAF9 has an M(r) of 36,000. With carboxymethyl cellulose as the substrate, the Vmax and Km values are 110 IU/mg of enzyme and 1.3 mg/ml, respectively. Comparison of primary amino acid sequences classifies CelB in the H family of cellulases.
从淡紫链霉菌IAF9培养滤液中分离出的内切葡聚糖酶CelB的相对分子质量为36000。以羧甲基纤维素为底物时,Vmax和Km值分别为110 IU/mg酶和1.3 mg/ml。通过对氨基酸一级序列的比较,CelB被归类于纤维素酶的H家族。
