In vivo assessment of the significance of phosphorylation of the Arabidopsis chloroplast protein import receptor, atToc33.

FEBS letters - 23 Jan 2006

Aronsson Henrik, Combe Jonathan, Patel Ramesh, Jarvis Paul

Abstract excerpt

atToc33 is a transit peptide receptor of the chloroplast outer envelope membrane, and possesses GTPase activity. In vitro, its transit peptide- and GTP-binding properties are abrogated by its phosphorylation at serine 181, which was proposed to represent an important regulatory mechanism. We mutated S181 to alanine (to prevent phosphorylation), and to aspartate and glutamate (to mimic the effects of...
