富含脯氨酸的细胞壁蛋白（proline-rich proteins,PRPs）在植物中广泛分布,它们在建造围绕特定细胞类型的细胞壁结构上起着很重要的作用.从棉花的cDNA文库中分离了5个编码富含脯氨酸的细胞壁蛋白质基因,这5个基因推断的氨基酸序列最普遍的特点就是脯氨酸含量非常高.根据氨基酸组成、富含脯氨酸的重复单元和结构域组织的特点,将这5个蛋白质分成2个亚类：一类（包括GhPRP3-6）与典型的PRPs结构相似,由N端疏水区（或信号肽）与不同富含脯氨酸的重复序列组成;另一类（GhPRPL）与典型的PRPs结构不同,这个蛋白质的N端为亲水序列,GhPRPL在靠近C端有8个5肽（类似PPKKE）的重复基序,与典型PRPs所含有的重...

Proline-rich cell wall proteins are widely spread in plants and are believed to function by modeling the architecture of the cell wall surrounding specific cell types. Five genes encoding proline-rich proteins were isolated from cotton cDNA libraries. The most common characteristic of these proteins is the abundant proline residues that occur in repeating motifs of at least two consecutive Pros. Based on amino acid composition, repetitive motifs and domain organization, the five members can be divided into two subgroups: one group similar to common PRPs including GhPRP3, GhPRP6, GhPRP5 and GhP...
