초록

Endogeneous endoglucanase (EC 3.2.1.4) cDNA was cloned from a representative species (Eisenia anderi) of the earthworm family Lumbricidae. Endoglucanase from the midgut of the earthworm is composed of 456 amino acids and belongs to glycosyl hydrolase family 9 (GHF9), sharing high homologies (50-51 %) with those of selected termite and crayfish. This endoglucanase consists of three consensus catalytic domains found in most microbial cellulases. A phylogenetic tree was constructed using the amino acid squence data matched through the BLASTX program and showed that GHF9 families could be divided into four groups of arthropoda, bacteria, plant and annelida.
