Abstract excerpt
The chloroplast protein CSP41a both binds and cleaves RNA, particularly in stem-loops, and has been found associated with ribosomes. A related protein, CSP41b, co-purifies with CSP41a, ribosomes, and the plastid-encoded RNA polymerase. Here we show that Arabidopsis CSP41a and CSP41b interact in vivo, and that a csp41b null mutant becomes depleted of CSP41a in mature leaves, correlating with a pale green phenotype...
