Abstract

The paper briefly describes the evolution of the key enzyme of photosynthesis, RuBisCO. Before the emergence of the reaction of carbon dioxide assimilation via photosynthesis, this protein was involved in the methionine metabolism chain. Possibly, for this reason, the carboxylation reaction catalyzed by enzyme proceeds very slowly. In addition to carboxylation, RuBisCO can simultaneously oxidize ribulose bisphosphate, a substrate to which the fixed CO₂ is attached. This, in turn, also reduces the effectiveness of photosynthesis. In this regard, the literature discusses various options for increasing plant productivity by creating new forms of RuBisCO or fundamentally different pathways of carbon dioxide assimilation. In this work, we propose a modification of the carboxylation reaction that makes it possible to avoid photorespiration and thus increase the efficiency of photosynthesis.

一种增加光合作用效率的可能途径。

摘要

本文简要介绍了光合作用的关键酶RuBisCO的演变。在通过光合作用产生二氧化碳同化反应之前，该蛋白质参与了蛋氨酸的代谢链。因此，可能由于酶催化的羧化反应进行得非常缓慢。除羧化作用外，RuBisCO还可以同时氧化核糖双磷酸核糖（一种固定了CO ₂的底物）被附上。反过来，这也降低了光合作用的效率。在这方面，文献讨论了通过创建新形式的RuBisCO或根本不同的二氧化碳吸收途径来提高植物生产力的各种选择。在这项工作中，我们提出了一种羧化反应的改进方案，可以避免光呼吸，从而提高光合作用的效率。
