Molecular cloning and characterization of a secretory neutral ceramidase of Drosophila melanogaster.

abstract：:When compared with collagens isolated from animal sources, collagens and collagen-like (CL) proteins from non-animal sources are non-immunogenic and thus promising as biomedical materials. Recently, a CL protein, V-CL, was identified from a bacterial source, Streptococcus pyogenes. In this study, an acid-precipitation...
