Oxidative enzymes and phosphatases in Agave vera Cruz Mill.

Per01ldase. catalase and phosphomonoesterase,
present in the stem of Agave vera
cruz Mill., have been studied. Partial purification
by fractional precipitation with anunonium
sulphate and dialysis results in a 30-fold
Increase in peroxidase activity, but only In a
2-fold increase in phosphomonoesterase activity,
on protein basis. The latter enzyIlle
shows two pH optima, one around pH 3'5 and
the other around pH 5·5. MagnesiumH did
not have any activating effect on either of the
acid phosphatases.
