Explain lyases

These enzymes (code EC 4) cleave C-C,  C-O, C-N  and other bonds by elimination, forming double bonds or conversely adding groups  to double bonds. Common names include decarboxylase, aldolase, dehydratase (if water is eliminated) or hydro-lyase (if  the reverse reaction  is more  important  or the  only  one  which can  be demonstrated). Spthase, but not  synthetase, may be used  as in  tryptophan synthase or cystathionine P-synthase.
