Figure 6

Metabolic pathways involved in malate metabolism in grape fruits during development. The protein levels of deregulated enzymes are shown in coloured squares, indicating the change of expression (log2 ratio) for each developmental stage in relation to the 15 mm stage. In sequence order (left to right), stages are displayed from FS, 4 mm, 7 mm, 15 mm, V-100, 110 g/l, and 140 g/l. Different isoforms or subunits of proteins are shown as different rows. The enzymes names for each biochemical step are indicated in red if differentially expressed and identified, or in black if not detected. Black solid and dashed arrows indicate enzymatic reactions and metabolite movement, respectively. SuSy, sucrose synthase; SuPSy, sucrose phosphate synthase; UDP-GP, UDP- glucose pyrophosphorylase; PFK-1: Phosphofructokinase-1; PFP, pyrophosphate-dependent phosphofructokinase; FK, fructokinase; HK, hexokinase; PGM, phosphoglucomutase; FBPA, fructose bisphosphate aldolase; TPI, triose phosphate isomerase; G3PDH, glyceraldehide-3-phosphate dehydrogenase; PGK, phosphoglycerate kinase; ENO, enolase; PGM, phosphoglycerate mutase; PK, pyruvate kinase; PEPC, phosphoenolpyruvate carboxylase; PEPCK, phosphoenolpyruvate carboxykinase; PPDK, pyruvate orthophosphate dikinase; cMDH, cytosolic malate dehydrogenase; cME, cytosolic malic enzyme; PDC, pyruvate decarboxylase; ADH, alcohol dehydrogenase; vINV, vacuolar acid invertase; VvHT6, hexose transporter 6; PDH, pyruvate dehydrogenase; mMDH, malate dehydrogenase mitochondrial; mME, mitochondrial malic enzyme; FH, fumarate hydratase; ATP-CL, ATP-citrate lyase; GS, glutamine synthase; GDH, glutamate dehydrogenase; DTC, dicarboxylate-tricarboxylate carrier.
