In order to spread infections, bacterial collagenases methodically unravel collagen fibril in tissues. Collagen is the most abundant protein in the body, and can be found in the skin, bone and cartilage [1]. Two collagenases, ColG and ColH, synergistically dismantle collagen fibrils by seeking different weak links in the collagen structure. The collagen-binding domain (CBD) of these collagenases binds to most vulnerable regions in collagen [8]. Without CBDs, collagen fibril cannot be degraded. Cells express collagen receptors in order to anchor themselves, which is a critical step in cell proliferation. Binding sites for some collagen receptors, such as integrin and …
