This list does not include all the known enzymes ; there are many 

 more amongst the carbohydrate splitting enzymes. 'The lipoclastic 

 enzymes can be subdivided into butyrinase, lecithinase. Xanthine 

 is oxidised to uric acid by uricase and a whole series of enzymes are 

 concerned in the hydrolysis of nucleic acid each acting upon a particular 

 substrate. They are grouped together as nucleases and would include 

 guanase and adenase as well as nucleotidases, etc.
