a biochemical and cytochemical study has been made of the distribution of beta-glycerophosphatase ( ec 3.1.3.2 ) activity in mature and differentiating phloem cells of nicotiana tabacum l. and the ph dependence and kinetics of beta-glycerophosphate hydrolysis of homogenates of fresh leaf midveins and midveins fixed in formaldehyde-gluteraldehyde . beta-glycerophosphatase showed two peaks of activity at ph 5.5 and 6.2 .
