Article Synopsis
  • Ras•GTP exists in two forms: an inactive state (state 1) and an active state (state 2), but understanding how it transitions between these states has been difficult due to a lack of structural data on state 1.
  • Newly solved crystal structures of wild-type H-Ras show the characteristics of both state 1 and state 2, revealing the state 2 structure may act as a bridge during the transition between the two states.
  • Analysis of the structural changes points to significant rearrangements in specific regions of the molecule, suggesting that interactions and movements of certain key residues and water molecules play critical roles in the transition, while biochemical studies indicate that state 1 may function as a stable reservoir in the GDP

Vibrio vulnificus is a halophilic marine microorganism which causes gastroenteritis and primary septicaemia in humans. An important factor that determines the survival of V. vulnificus in the human body is its ability to acquire iron.

Human Lyn tyrosine kinase is expressed in hematopoietic tissues and plays crucial roles in the signal transduction of hematopoietic immune system. Its excess activity is involved in several tumors. The crystal structure has revealed that the potent inhibitor staurosporine binds to human Lyn kinase domain at the ATP-binding site.
