Figure 4.

Maximum catalytic activities of enzymes of carboxylic acid metabolism in fruit from cv M82 and IL2-5. Enzyme activities are shown for isolated mitochondria (A) and crude pericarp extracts (B) from 40-DAA fruit. Data are means ± se (n = 3). For clarity, the NAD-malate dehydrogenase activity is divided by 10. *Significantly different from cv M82 (Student’s t test, P < 0.05). DH, Dehydrogenase; ICDH, isocitrate dehydrogenase; 2-OGDH, 2-oxogluratate dehydrogenase. Coenzyme specificity is indicated where relevant.
