Proteins identified by MudPIT analysis. A total of 411 proteins were identified in the six examined strains. Putative membrane proteins (35%) have conserved domains with known or predicted membrane proteins in other organisms, 28% are hypothetical proteins with transmembrane domain (TMD) and/or signal peptide (SP), 9% represent hypothetical proteins without transmembrane domain or signal peptide, 23% represent suspected protein contaminants, and 5% were classified as membrane-associated proteins and are largely cytoskeleton proteins.
