3igu Summary


Crystal structure of human alpha-N-acetylgalactosaminidase, covalent intermediate

The structure was published by Clark, N.E. and Garman, S.C., in 2009 in a paper entitled "The 1.9 a structure of human alpha-N-acetylgalactosaminidase: The molecular basis of Schindler and Kanzaki diseases" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.15 Å and deposited in 2009.

The experimental data on which the structure is based was also deposited.
