纤维素酶 cellulase

　　纤维素酶 cellulase 催化纤维素水解的酶（ EC3． 2． 1． 4）．发现于高等植物的芽、青霉、酵母、菌或木材腐朽菌那种霉菌和许多土壤细菌。此酶还存在于牛胃等高等动物的消化道内，这是由于栖息在消化道内的原生动物以及其他微生物产生的。在低等动物中，蜗牛的胃液和凿船贝的消化盲囊等的消化液中含有自己产生的酶。又已知在某些昆虫（ Macrotoma的一种等）也有同样的纤维素酶。许多木材穿孔性昆虫及其幼虫的消化道内存在着许多微生物（例如：白蚁的 Trichonym－ pha

Cellulase Processivity

a mutation in Cel6B was identified that appears to allow the mutant enzyme to move along a cellulose chain in the absence of cleavage.

Cellulase assays

Cellulase enzymes show activity during the ripening of some fruits, where their effects on cell walls results in softening of the fruit. In cases of programmed cell death, such as the formation of aerenchyma (large air spaces
