Abstract

The DNA sequences of the Thermomonospora fusca genes encoding cellulases E2 and E5 and the N-terminal end of E4 were determined. Each sequence contains an identical 14-bp inverted repeat upstream of the initiation codon. There were no significant homologies between the coding regions of the three genes. The E2 gene is 73% identical to the celA gene from Microbispora bispora, but this was the only homology found with other cellulase genes. E2 belongs to a family of cellulases that includes celA from M. bispora, cenA from Cellulomonas fimi, casA from an alkalophilic Streptomyces strain, and cellobiohydrolase II from Trichoderma reesei. E4 shows 44% identity to an avocado cellulase, while E5 belongs to the Bacillus cellulase family. There were strong similarities between the amino acid sequences of the E2 and E5 cellulose binding domains, and these regions also showed homology with C. fimi and Pseudomonas fluorescens cellulose binding domains.
