The proteome of the chloroplast lumen of higher plants.

Author information

Recent research in proteomics of the higher plant chloroplast has achieved considerable progress and added to our knowledge of lumenal chloroplast proteins. This work shows that chloroplast lumen has its own specific proteome and may comprise as many as 80 proteins. Although the new map of the lumenal proteome provides a great deal of information, it also raises numerous questions because the physiological functions of most of the novel lumenal proteins are unknown. In this Minireview, we summarize the latest discoveries regarding lumenal proteins and present the currently known facts about the lumenal chloroplast proteome of higher plants.
