摘要

通过使用蛋白质组学,发现自养、好氧的紫色硫细菌那不勒斯卤硫杆菌在从碳酸氢盐转换为CO2(g)作为碳源时,其部分二氧化碳吸收和固定机制的细胞水平发生了变化。这包括异二聚碳酸氢盐转运蛋白水平的增加,以及RubisCO的I型和II型之间的潜在转换。在几种硫氧化途径中可以看到额外的变化,这可能表明硫氧化途径作为能源与碳吸收/固定机制之间存在联系。

Proteomics of Carbon Fixation Energy Sources in Halothiobacillus neapolitanus
Through the use of proteomics, it was uncovered that the autotrophic, aerobic purple sulfur bacterium Halothiobacillus neapolitanus displays changes in cellular levels of portions of its carbon dioxide uptake and fixation mechanisms upon switch from bicarbonate to CO2(g) as carbon source. This includes an increase in level of a heterodimeric bicarbonate transporter along with a potential switch between form I and form II of RubisCO. Additional changes are seen in several sulfur oxidation pathways, which may indicate a link between sulfur oxidation pathways as an energy source and carbon uptake/fixation mechanisms.
