enzymic activity is present in cells grown on arabinose but not glucose and mRNA expression is induced 185fold during growth on arabinose when compared to growth on glucose

2 entries

the induction with different sugars indicates that the transcription of mpk1 can be upregulated by xylose, hexose sugars (glucose and galactose) or disaccharides (sucrose and trehalose) but not by mannitol, sorbose or sorbitol
