CasA is an endo-beta-1,4-glucanase from Streptomyces KSM-9 belonging to family B of beta-1,4-glucanases. A previous analysis of a portion of the corresponding gene (casA) revealed sequencing errors in a region encoding part of the catalytic site. Additional errors in the original sequence were suspected, based on sequence comparison of the C terminus of CasA with other members of its family. Re-sequencing of the remainder of the casA coding region showed that CasA is a typical member of family B.
CasA是一种来自链霉菌KSM-9的内切β-1,4-葡聚糖酶，属于β-1,4-葡聚糖酶家族B。先前对相应基因（casA）部分区域的分析揭示了编码催化位点一部分的区域存在测序错误。基于CasA C末端与家族其他成员的序列比较，怀疑原始序列中存在其他错误。对casA编码区其余部分的重新测序表明，CasA是家族B的典型成员。
