Thesco6545 gene ofStreptomyces coelicolor A3(2) was nominated as a putative cellulase with 863 mature-form amino acids (90.58 kDa). We overexpressed and purified Sco6545 and demonstrated that the protein is not a cellulase but a xyloglucan-specific glycosyl hydrolase which cleaves xyloglucan at unbranched glucose residues.
