pseudotuberculosis exoproteome as the input sequences. Additionally, transitivity clustering [82] was used to identify proteins (i) commonly detected in the exoproteomes of pathogenic and non-pathogenic corynebacteria, and proteins detected in exoproteomes of (ii) only pathogenic corynebacteria or (iii) only C. pseudotuberculosis. A more detailed description on the transitivity clustering analysis can be found in the supplementary material (additional file 9). The amino acid sequences of the identified C. pseudotuberculosis exoproteins were also used in similarity searches against public databases, namely NCBI nr and Swissprot. Transcriptional regulation of GS-1101 molecular weight the identified exoproteins

The search for transcription factors that regulate expression of the

identified corynebacterial exoproteins was performed through the CoryneRegNet database, as described previously [83]. Accession numbers The sequences of all proteins identified in this work are accessible through GenBank and correspond to the Corynebacterium pseudotuberculosis Genome Projects deposited in NCBI (IDs: selleck products 40687 and 40875).

(A) 2D-gel with 150 μg of TPP extracted extracellular

proteins of the 1002 strain. Proteins were separated in the first dimension by isoelectric focusing using strips of 3.0-5.6 NL pI range (GE Healthcare). Visualization was by Colloidal Coomassie staining. (B) The virtual 2D-gel was generated with the theoretical pI and MW values of the proteins identified by LC-MSE.
