Organism

Methanothermus fervidus (strain ATCC 43054 / DSM 2088 / JCM 10308 / V24 S) [Complete proteome] [HAMAP]

Taxonomic identifier

523846 [NCBI]

Taxonomic lineage

Archaea › Euryarchaeota › Methanobacteria › Methanobacteriales › Methanothermaceae › Methanothermus

Protein attributes

Sequence length	339 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Acts on oxaloacetate, sulfopyruvate but not on pyruvate. Has a higher selectivity for the coenzyme NADH than for NADPH. Ref.3
Catalytic activity	(S)-malate + NAD+ = oxaloacetate + NADH. (S)-malate + NADP+ = oxaloacetate + NADPH. (2R)-3-sulfolactate + NAD(P)+ = 3-sulfopyruvate + NAD(P)H.
Subunit structure	Homodimer.
Subcellular location	Cytoplasm.
Sequence similarities	Belongs to the LDH2/MDH2 oxidoreductase family.
