which might be due to the hydrolytic activity of proteases or post- translational modifications (Finnie and Svensson 2002; Nouwens et al., 2003).The SLH-domain protein of high-molecular weight (127 kDa), contains two N-terminal SLH domains of approximately 65 aminoacids and a large C-terminal uncharacterized region. While proteins with SLH domains have been described as part of cellulo- somes and in some cell-surface enzymes of Gram positive bacteria (Desvaux et al., 2006; Blumer-Schuette et al., 2010), their role in polysacharides deconstruction in aerobic bacteria is unclear. A 67 kDa solute-binding protein, with similarity to soluble proteins from ABC type sugar transport system was also identified in the
