X-ray Crystallography Technique Helps Identify Protein Binding Sites (image) Advanced Science Research Center, GC/CUNY Share Print E-Mail Caption A high-throughput method reveals where over 100 small molecules bind to the protein PTP1B. A select few of these binding areas can send signals to the active site (red) to control PTP1B's activity."
