Purpose: To determine the level of proteolytic activity in lens epithelium samples from cataract surgery and to investigate a possible relation to the type of cataract. We wanted to estimate G-independent as well as Ca-dependent activity. Another purpose was to me.asure the activity of calpastatin, an endogenous inhibitor of calpain, which is a Ca-activated protease. Methods: Cataracts were typ...

teins of the body and it is present in the skin, blood vessels, organs, bone and connective tissue. Collagen also accounts for approximately 70% of the dermal structural ingredient of skin and it is the primary ingredient of the extracellular matrix surrounding the outer membrane of the cell body (scaffold) which supports the cell population. Gelatin on the other hand is collagen with a triple ...

When the HhaI (cytosine-5) methyltransferase (M.HhaI) binds DNA it causes the target cytosine to be flipped 180 degrees out of the helix. The space becomes occupied by two amino acids, Ser-87 and Gln-237, which enter the helix from opposite sides and form a hydrogen bond to each other. Gln-237 may be involved in specific sequence recognition since it forms three hydrogen bonds to the orphan gua...
