Zusammenfassung

Diatoms are unicellular photoautotrophic algae and very successful primary producers in the oceans. Their high primary productivity is probably sustained by their high adaptability and a uniquely arranged metabolism. Diatom belongs to the Chromista, a large eukaryotic group, which has evolved by multiple endosymbiotic steps. As a result, diatoms possess a plastids with four membranes together with complicated translocation systems to transport proteins and metabolites including inorganic substances into and out of the plastids. In addition to the occurrence of potential plasma-membrane transporters, there are numerous carbonic anhydrases (CAs) within the matrix of the layered plastidic membranes, strongly suggesting large interconversion activity between CO₂ and HCO₃− within the chloroplast envelope as a part of a CO2-concentrating mechanism (CCM). In diatoms also the Calvin cycle and its adjacent metabolism reveal unique characteristics as, for instance, ribulose-1,5-bisphosphate carboxylase/oxygenase (RubisCO) activase, the plastidic sedoheptulose-1,7-bisphosphatase (SBPase), and the plastidic oxidative pentose phosphate pathway (OPP) are absent. Furthermore, the Calvin cycle metabolism in diatoms is not under the strict redox control by the thioredoxin (Trx) system. Instead, a CO₂-supplying system in the pyrenoid shows CA activities which are probably regulated by chloroplastic Trxs. Pyrenoidal CAs are also regulated on the transcriptional level by CO₂ concentrations via cAMP as a second messenger, suggesting an intense control system of CO₂ acquisition in response to CO₂ availability. The photorespiratory carbon oxidation cycle (PCOC) is the major pathway to recycle phosphoglycolate in diatoms although this process might not be involved in recycling of 3-phosphoglycerate but instead produces glycine and serine. In this review we focus on recent experimental data together with supportive genome information of CO₂ acquisition and fixation systems primarily in two marine diatoms, Phaeodactylum tricornutum and Thalassiosira pseudonana.
