TRANSAMINASE ACTIVITY IN PLANTS

Transaminase activity  (alanine  ->  glutamic,  aspartic  ->  glutamic,  glutamic  ->  alanine)  has  been  detecled  in  a  number of  pulses. An  easy  and  specific  method for the determination of  aminase  using circular paper  chromatography  is  described. The  optimum  pH  for  alanine -> glutanlic  acid  transaminase  is  found  to  be  7 ·4, Germination control  increases  the  enzyme  activity  (alanine ->  glutamic). Inhibition of  the  transaminase  activity  by  pterygospermin  has  been  reported  for the  first  time  and  the  hearing  of  this  result  on  the  antibiotic  action  of  pterygospermin  is  indicated.
