Cloning, characterisation and regulation of the ornithine transaminase (otaA) gene of Aspergillus nidulans.

abstract：:Most eukaryotes require molecular oxygen for growth. In general, oxygen is the terminal electron acceptor of the respiratory chain and represents an important substrate for the biosynthesis of cellular compounds. However, in their natural environment, such as soil, and also during the infection, filamentous fungi are ...
