Molecular cloning of the yeast OPI3 gene as a high copy number suppressor of the cho2 mutation.

abstract：:The ornithine transaminase (otaA) gene of Aspergillus nidulans has been cloned by transformation of the A. nidulans pro-ota- mutant strain with a cosmid gene library. The otaA gene contains two introns and potentially codes for a 453-aa-long protein. The deduced amino-acid sequence is homologous to known ornithine tra...
