ABSTRACT
The new suggestion for the naming of different cellulases is based purely on their assignment to these glycosyl hydrolase families (11). If there is more than one enzyme belonging to the same family from one organism, the enzymes are further named with running alphabets in the order that they have been classified. For example Trichoderma reesei Cel7A (CBH I) and Cel7B (EG I) are two cellulose degrading enzymes in the glycosyl hydrolase family 7. In this chapter, the old naming system using endoglucanases and cellobiohydrolases is used since most publications still use this nomenclature.
