文摘

A new endogenous earthworm cellulase, Ean-EG, and its expression pattern are demonstrated. Deduced amino acid sequence comprises the conserved region specific to GHF9 containing the essential amino acid residues for enzyme activity. Ean-EG expression was observed in epidermis, chloragogue tissue cells, coelomic cell-aggregate, and even blood vessel. Cellulase function could not be limited to digestive process but be possibly extended to the innate immunity.
