Sequence of the GLT1 gene from Saccharomyces cerevisiae reveals the domain structure of yeast glutamate synthase

Glutamate synthase (GOGAT) and glutamine synthetase play a crucial role in ammonium assimilation and glutamate biosynthesis in the yeast Saccharomyces cerevisiae. The GOGAT enzyme has been purified and the GOGAT structural gene (GLT1) has been cloned, showing that this enzyme is a homotrimeric protein with a monomeric size of 199kDa.
