| Type: | Family | Name: | Chloroplast protein import component Toc86/159 |
| Description: | Two integral outer envelope GTPases, Toc34 and Toc86, are proposed to regulate the recognition and translocation of nuclear-encoded preproteins during the early stages of protein import into chloroplasts. The long precursor of the 86K protein (corresponding to a native protein of 159 kDa termed Toc159) is proposed to have three domains. The N-terminal A-domain is acidic, repetitive, weakly conserved, readily removed by proteolysis during chloroplast isolation, and not required for protein translocation []. The other domains are designated G (GTPase) and M (membrane anchor) []. The signature for this family includes most of the G domain and all of M. | Short Name: | Toc86_159 |
