S. Madan et Hs. Nainawatee, Properties of partially purified leaf ornithine aminotransferase of Brassica juncea under salt stress, ACT PHYS PL, 22(4), 2000, pp. 445-450
Properties of the partially purified L-ornithine: 2-oxoacid aminotransferas
e (EC 2.6.1.13) of leaves of Brassica juncea salt tolerant somaclone SR3P6-
2 and its parent cv. Prakash were studied. The enzyme from the somaclone SR
3P6-2 was relatively more efficient in terms of its Km, Vmax, and Ea (activ
ation energy) and required higher levels of chlorides for inhibition as com
pared to the enzyme from the parent cv. Prakash. These results suggest some
salt-stress related changes in the enzyme.
