Mutated cellulase of thermomonospora spp.

摘要

A mutant cellulase obtainable from Thermomonospora spp. is provided which differs from a precursor cellulase in that it has been genetically engineered to introduce a substitution, deletion or addition of an amino acid residue to said precursor cellulase which provided improved activity in a detergent. Preferably, the substitution is at a residue corresponding to T140 in Thermomonospora fusca.
