Аннотация:Intact chloroplasts were prepared from protoplasts of the moss Physcomitrella patens according to an especially
developed method. They were additionally separated into stroma and thylakoid fractions. The proteomes of intact plastids,
stroma, and thylakoids were analyzed by 1Delectrophoresis under denaturing conditions followed by protein digestion and
nanoLCESIMS/MS of tryptic peptides from gel bands. A total of 624 unique proteins were identified, 434 of which were
annotated as chloroplast resident proteins. The majority of proteins belonged to a photosynthetic group (21.3%) and to the
group of proteins implicated in protein degradation, posttranslational modification, folding, and import (20.6%). Among
proteins assigned to chloroplasts, the following groups are prominent combining proteins implicated in metabolism of:
amino acids (6.9%), nucleotides (2.5%), lipids (2.2%), carbohydrates (2.4%), hormones (1.5%), isoprenoids (1.25%), vita
mins and cofactors (1%), sulfur (1.25%), and nitrogen (1%); as well as proteins involved in the pentosephosphate cycle
(1.75%), tetrapyrrole synthesis (3.7%), and redox processes (3.6%). The data can be used in physiological and photobio
logical studies as well as in further studies of P. patens chloroplast proteome including structural and functional specifics of
plant protein localization in organelles.
