叶绿体核糖体

PSRP-1（S30／S22）是由核基因组编码的叶绿体核糖体特有的蛋白，组成叶绿体核糖体的30S小亚基。

PSRP-1 encoded by the nuclear genome constitutes the 30S subunit of chloroplast ribosomes .

高等植物叶绿体核糖体上有6个特殊蛋白质，是质体特异性核糖体蛋白质（PSRPs）。

Six ribosomal proteins are specific to higher plant chloroplast ribosomes . These proteins are plastid-specific ribosomal proteins ( PSRPs ) .
