[Advances in actinobacterial proteomics]

Abstract

Protein is the executor of physiological function, and direct embodiment of the life phenomena. Proteomics aims to systematically clarify all or parts of proteins' role and function in life movement. In post genome era, proteomics began to play more important role in life science field. Actinobacteria are closely linked to human production and life, which have produced many clinically important secondary metabolites, including antibiotics, antitumorals and enzymes. Actinobacterial systematics and its model organism Streptomyces coelicolor in 2001 genome sequence laid the foundation for further functional genomic studies. Actinobacterial proteomics was more directly and exactly to interpret the activity of life than genomics and transcriptomics, which grew much faster and received so much attention from scientists in the near years. Complex morphological differention, stronge environment adaptiveness, nitrogen-fixing capacity, metabolic mechanism, pathogenicity and natural produces' discovery were systematically reviewed in this study, which was expected to be the basis for promoting Actinobacterial proteomics study in the near future.
