Chemical process of decomposition during early decomposition, while others are degraded during later stages of decomposition. During the early stages of decomposition, soft tissue proteins are broken down. These include proteins that: During later stages of decomposition, more resistant tissue proteins are degraded by the effects of putrefaction. These include: Keratin is a protein which is found in skin, hair, and nails. It is most resistant to the enzymes involved in proteolysis and must be broken down by special keratinolytic microorganisms. This is the reason that hair and nails are commonly found with skeletal remains. In general, proteolysis breaks down proteins into: Continuing proteolysis
Virulence-related outer membrane protein family invasion and helps defend against the complement system. Although OmpX has the same beta-sheet topology as the structurally related outer membrane protein A (OmpA) , their barrels differ with respect to the shear numbers and internal hydrogen-bonding networks. OspA from Borrelia burgdorferi is an unusual outer surface protein, it has two globular domains which are connected with a single-layer β-sheet. This protein is highly soluble, contains a large number of Lys and Glu residues. These high entropy residues may disfavor crystal packing. Virulence-related outer membrane protein family Virulence-related outer membrane proteins are expressed in Gram-negative bacteria and are essential to
