Abstract
Contrary to earlier reports, CO(2) fixation by extracts of Chlamydomonas is inhibited by glutamate and aspartate. These amino acids and some organic acids are shown to be inhibitors of phosphoenolpyruvate carboxylase. Inorganic phosphate is shown to activate CO(2) fixation, but there is a time lag before inorganic phosphate exerts its full activating effect.
摘要
与早期报道相反，衣藻提取物对二氧化碳的固定受到谷氨酸和天冬氨酸的抑制。这些氨基酸和一些有机酸被证明是磷酸烯醇式丙酮酸羧化酶的抑制剂。无机磷酸盐被证明可激活二氧化碳的固定，但在无机磷酸盐发挥其完全激活作用之前存在时间滞后。
