English: Schematic representation of thylakoid protein targeting pathways:
Toc and Tic: translocon of outer and inner envelope membrane of chloroplasts, respectively
1. SRP (signal recognition particle) pathway; required GTP and pH gradient as energy source
2. ΔpH/Tat pathway; requires pH gradient as energy source
3. Sec (secretory system) pathway; required ATP as energy source
not shown: spontaneous insertion of transmembrane proteins requiring no energy source
Chloroplast targeting peptide shown in yellow is cleaved off by a processing protease after entering the chloroplast. Thylakoid targeting peptide shown in blue may be cleaved off (lumenal proteins) or not (membrane proteins).

It is recommended to name the SVG file "Thylakoid targeting.svg" - then the template Vector version available (or Vva) does not need the new image name parameter.
