KEGG   ENZYME: 1.1.1.299Help
Entry
EC 1.1.1.299                Enzyme                                 

Name
malate dehydrogenase [NAD(P)+];
MdH II, NAD(P)+-dependent malate dehyrogenase
Class
Oxidoreductases;
Acting on the CH-OH group of donors;
With NAD+ or NADP+ as acceptor
BRITE hierarchy
Sysname
(S)-malate:NAD(P)+ oxidoreductase
Reaction(IUBMB)
(S)-malate + NAD(P)+ = oxaloacetate + NAD(P)H + H+ [RN:R00342 R00343]
Reaction(KEGG)
Substrate
(S)-malate [CPD:C00149];
NAD+ [CPD:C00003];
NADP+ [CPD:C00006]
Product
oxaloacetate [CPD:C00036];
NADH [CPD:C00004];
NADPH [CPD:C00005];
H+ [CPD:C00080]
Comment
This enzyme, which was characterized from the methanogenic archaeon Methanobacterium thermoautotrophicum, catalyses only the reduction of oxaloacetate, and can use NAD+ and NADP+ with similar specific activity [1].
Different from EC 1.1.1.37 (malate dehydrogenase (NAD+)), EC 1.1.1.82 (malate dehydrogenase (NADP+)) and EC 1.1.5.4 (malate dehydrogenase (quinone)).
