Thông tin tài liệu:
Mature, active mammalian histidine decarboxylase is a di-meric enzyme of carboxy-truncatedmonomers (53 kDa).By using a biocomputational approach, we have generatedathree-dimensional model of a recombinant 1/512 fragmentof the rat enzyme, which shows kinetic constants similar tothose of the mature enzyme purified from rodent tissues.This model, together with previous spectroscopic data, al-lowed us to postulate that the occupation of the catalyticcenter by the natural substrate, or by substrate-analogs,would induce remarkable changes in the conformation ofthe intact holoenzyme....
