STRUCTURE OF HUMAN TRYPSIN IV (BRAIN TRYPSIN)
Overview
Severe neurodegradative brain diseases, like Alzheimer, are tightly linked, with proteolytic activity in the human brain. Proteinases expressed in the, brain, such as human trypsin IV, are likely to be involved in the, pathomechanism of these diseases. The observation of amyloid formed in the, brain of transgenic mice expressing human trypsin IV supports this, hypothesis. Human trypsin IV is also resistant towards all studied, naturally occurring polypeptide inhibitors. It has been postulated that, the substitution of Gly193 to arginine is responsible for this inhibitor, resistance. Here we report the X-ray structure of human trypsin IV in, complex with the inhibitor benzamidine at 1.7 A resolution. The overall, fold of human trypsin IV is similar to human trypsin I, with a root-mean, ... [(full description)]
