2hv6 Summary


Crystal structure of the phosphotyrosyl phosphatase activator

The structure was published by Chao, Y., Xing, Y., Chen, Y., et al., Jeffrey, P.D., Stock, J.B., and Shi, Y., in 2006 in a paper entitled "Structure and mechanism of the phosphotyrosyl phosphatase activator." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 2006.

The experimental data on which the structure is based was not deposited.
