A gene of unknown function identified in , Gohir.A03G0737001.1, was studied using sequence and bioinformatic tools. The encoded protein (referred to here as GhCPP1-A0A1U8HKT6) was predicted to function as a Chaperone-like protein of protochlorophyllide oxidoreductase (CPP1), which is involved with initiation of photochemical reactions of chlorophyll biosynthesis. Sequence analysis indicates it is embedded in the chloroplast envelope membrane through four transmembrane regions and contains a J-like domain that is structurally similar to the J domain of DnaJ/Hsp40 "holdase" chaperone proteins.
对在[具体内容未给出]中鉴定出的一个功能未知的基因Gohir.A03G0737001.1，使用序列和生物信息学工具进行了研究。预测编码的蛋白质（此处称为GhCPP1 - A0A1U8HKT6）作为原叶绿素酸氧化还原酶（CPP1）的伴侣样蛋白发挥作用，该酶参与叶绿素生物合成的光化学反应起始过程。序列分析表明，它通过四个跨膜区域嵌入叶绿体包膜膜中，并包含一个J样结构域，其结构与DnaJ/Hsp40“保持酶”伴侣蛋白的J结构域相似。
