For far too long, the chloroplast has been keeping the spotlight squarely on himself. Everybody knows what a chloroplast is, but many fail to realize that the chloroplast is just one type of the organelles known as plastids. Plprot, the plastid protein database, features three types of plastids in addition to the chloroplast: the proplastid (the precursor to all other plastids), the etioplast (basically a chloroplast, but one that has not been exposed to light), and the chromoplast (used for the synthesis and storage of pigment). Plprot features an introduction to each of these plastids, in addition to the database. The database stores information on about 2,650 entries for proteins identified in proteomics studies, and it can be searched according to plprot identifier, gene identifier, author of the paper in which the protein was reported, NCBI protein annotation, or protein sequence.
