[Lysine overproduction mutations in the yeast Saccharomyces cerevisiae and its transfection into industrial Yeast strains ].

Yeast mutants resistant to a toxic lysine analog, thialysine were obtained by a method described in the literature. A strain excreting the maximum amount of lysine (0.45 g/l) was selected from these mutants.

UVS112--A gene involved in excision repair of yeast.

In this study we show that the previously described uvs112 (uvs12) mutation blocks one of the steps of the excision repair pathway. The properties of this mutation permit the assignment of the UVS112 gene to the RAD3 epistasis group. It was established that the uvs112 mutation caused a 2.
