Cloning of a cellulase gene from the rumen anaerobe Fibrobacter succinogenes SD35 and partial characterization of the gene product.
A gene encoding an enzyme which degrades cellulose (end-1) was isolated from a library of Fibrobacter succinogenes SD35 DNA fragments and expressed in pUC18. The product of end-1 showed significant activity against carboxymethylcellulose but relatively minor activity against lichenan, xylan and avicel. The nucleotide sequence indicated a product of 388 amino acids with a molecular mass of 50.2 kDa. This was in agreement with the molecular size estimated by gel electrophoresis. No significant DNA sequence similarity was identified with any published endoglucanase.
