In vitro comparative kinetic analysis of the chloroplast Toc GTPases.

The Journal of biological chemistry - 13 Apr 2007

Reddick L Evan, Vaughn Michael D, Wright Sarah J, Campbell Ian M, Bruce Barry D

Abstract excerpt

A unique aspect of protein transport into plastids is the coordinate involvement of two GTPases in the translocon of the outer chloroplast membrane (Toc). There are two subfamilies in Arabidopsis, the small GTPases (Toc33 and Toc34) and the large acidic GTPases (Toc90, Toc120, Toc132, and Toc159). In chloroplasts, Toc34 and Toc159 are implicated in precursor binding, yet mechanistic details are poorly understood....
