1970 Journal of Bacteriology  
An endo-N-acetyl-glucosaminidase which degrades the murein (peptidoglycan) sacculi of the cell walls of Escherichia coli and Spirillum serpens, but not those of Micrococcus lysodeikticus and Sarcina lutea, is present as a contaminant in a "phospholipase C" from Clostridium perfringens. The specificity of enzyme action was elucidated by reduction of liberated glycosidic groups with NaBH4 and identification of glucosaminol as the reduction product. This finding contradicts previous reports
