L-alanine + H2O + NAD+ = pyruvate + NH3 + NADH + H+
reductive amination: sequential mechanism with partially random binding
-
L-alanine + H2O + NAD+ = pyruvate + NH3 + NADH + H+
reductive amination proceeds through a sequential mechanism containing partially random binding. NADH binds first to the enzyme, and then pyruvate and ammonia bind in a random fashion
-
L-alanine + H2O + NAD+ = pyruvate + NH3 + NADH + H+
predominantly ordered kinetic mechanism in which NAD+ adds before L-Ala, and ammonia, pyruvate, and NADH are released in that order
-
L-alanine + H2O + NAD+ = pyruvate + NH3 + NADH + H+
sequential ordered ternary-binary mechanism, the enzyme is A-stereospecific, the pro-R hydrogen at C-4 of the reduced nicotinamide ring of NADH is exclusively transferred to pyruvate
-
L-alanine + H2O + NAD+ = pyruvate + NH3 + NADH + H+
the kinetic mechanism at pH 8.5 is determined to be ter-bi Theorell-Chance. In the amination direction, the substrates add in the order: NADH, NH4+, pyruvate, with NH4+ binding in rapid-equilibrium. In the reverse direction, NAD adds first followed by L-Ala
-
L-alanine + H2O + NAD+ = pyruvate + NH3 + NADH + H+
oxidative deamination proceeds by an random-ordered mechanism
-
L-alanine + H2O + NAD+ = pyruvate + NH3 + NADH + H+
sequential ordered binary-ternary mechanism. NAD+ binds first to the enzyme, followed by L-Ala. The products are released in the order: NH4+, pyruvate and NADH
-
L-alanine + H2O + NAD+ = pyruvate + NH3 + NADH + H+

transfer of hydride is a partially limiting step and the reaction rate is limited by the release of product NADH. The fluorine constituent doesn't cause a significant change in the area of bonds that are being converted, and deuteriated solvent present in the reaction medium only slightly affects the conversion of [E-S] complex into [E-P] complex
