Abstract

This entry represents a group of pentapeptide repeat containing proteins (PRPs) from plants and cyanobacteria, including At2g44920 (also known as p15) from Arabidopsis [ 1 ]. PRP structures are dominated by four-sided right-handed beta-helices typically consisting of mixtures of type II and type IV beta-turns. At2g44920 is a thylakoid lumenal protein that consists of 25 pentapeptide repeats capped by N- and C-terminal alpha-helices. Unlike other PRPs, At2g44920 consists exclusively of type II beta-turns [ 2 ].
