<abstract xmlns="http://www.w3.org/1999/xhtml">Existence of moonlighting proteins in microorganisms is a known phenomenon, yet still not well understood. Moonlighting proteins have at least two independent biological functions, which must be performed by one polypeptide chain without separation into protein domains. Most of these proteins, beside their role in the cytoplasm, play an important role outside of the cell i.e. they take part in the process of pathogenesis by binding and activating host’s plasminogen. The existence of moonlighting proteins complicates the understanding of pathogenicity and virulence of many common bacteria as well as their role in commensal bacteria. Many of moonlighting proteins occurring in commensal bacteria appear to perform similar functions to proteins discovered in pathogenic bacteria, e.g. binding extracellular matrix.
