The Crystal Structure of the Double-headed Arrowhead Protease Inhibitor A in Complex with Two Trypsins
The structure was published by Bao, R., Zhou, C.Z., Jiang, C.-H., Lin, S.X., Chi, C.W., and Chen, Y.X., in 2009 in a paper entitled "The ternary structure of double-headed arrowhead protease inhibitor API-A complexed with two trypsins reveals a novel reactive site conformation." (abstract).
This crystal structure was determined using X-ray diffraction at a resolution of 2.48 Å and deposited in 2008.
The experimental data on which the structure is based was also deposited.
