Chicken liver glutamic dehydrogenase.

During the course of fractionation of chicken liver extracts, it was observed that glutamic dehydrogenase could be obtained in the crystalline form after a few simple purification steps. The procedure used in the isolation of glutamic dehydrogenase of chicken liver as well as some of the properties of the crystalline enzyme are described in the present communication. Although the chicken liver enzyme appears to be similar to the crystalline glutamic dehydrogenase from beef liver (l-3) previously described, the present results are reported in view of the simplicity of the isolation procedure and the availability of the starting material.
