Figure 6: Carbon-concentrating mechanisms.
From: Draft genome sequence and genetic transformation of the oleaginous alga Nannochloropsis gaditana
Proposed mechanisms in which inorganic carbon is assimilated by N. gaditana and the proposed C4-like metabolism based on predicted protein localizations. Metabolites (black): G3P, glyceraldehyde 3-phosphate; MA, malic acid; OAA, oxaloacetate; PEP, phosphoenolpyruvate; 3-PGA, 3-phosphoglycerate; Pyr, pyruvate; RuBP, ribulose-1,5-bisphosphate; Enzymes (red): BCT, bicarbonate transporter; CA, carbonic anhydrase; MDH, malate dehydrogenase; ME, malic enzyme; PC, pyruvate carboxylase; PEPC, phosphoenolpyruvate carboxylase; PPDK, pyruvate, phosphate dikinase; RuBisCO, Ribulose-1,5-bisphosphate carboxylase oxygenase.
