Arabidopsis thaliana mutants reveal a role for CSP41a and CSP41b, two ribosome-associated endonucleases, in chloroplast ribosomal RNA metabolism.

Plant molecular biology - 1 Jul 2008

Beligni María Verónica, Mayfield Stephen P

Abstract excerpt

A proteomic analysis of Chlamydomonas reinhardtii 70S ribosomes identified two proteins, RAP38 and RAP41, which associate in stoichiometric amounts with intact ribosomes. In this work we show results that suggest the Arabidopsis thaliana homologs, CSP41b and CSP41a, participate in ribosomal RNA metabolism. Csp41a-1 and csp41b-1 single mutants show little phenotype, while the loss of both proteins is lethal....
