1.1.2.4	carboxylic acid	activates, stimulation is non-competitive, hyperbolic and its dimension is directly related to the number of carboxylic groups on the activator. Stimulation does not affect the yield of oxidative phosphorylation	
1.1.2.4	D-lactate	stimulation with D-lactate as substrate, is insensitive to malate or pyruvate addition	
1.1.2.4	EDTA	slightly stimulating	
1.1.2.4	L-malate	non-competitive activation	
1.1.2.4	additional information	growth on lactate and ethanol yields much higher activities than grows on glucose	
1.1.2.4	additional information	the enzyme is induced by lacate as sole carbon source during growth
