Multiple fungal enzymes possess cysteine synthase activity in vitro.

Research in microbiology - 1 Jun 2007

Brzywczy Jerzy, Natorff Renata, Sieńko Marzena, Paszewski Andrzej

Abstract excerpt

We present evidence that there are at least three Aspergillus nidulans enzymes which catalyze in vitro the reaction of O-acetylserine (OAS) with sulfide forming cysteine. This activity is shared by cysteine synthase (CS) encoded by the cysB gene, homocysteine synthase encoded by cysD and by at least one more enzyme. Moreover, arginine, histidine or proline starvation leads to derepression of CS activity even in...
