|Gene:||LGA1||Accession Number: G-11976 (MetaCyc)|
Species: Trichoderma reesei
The subunit structure of this enzyme from Trichoderma reesei (previously known as Hypocrea jecorina) has not been reported.
Recombinant enzyme was expressed in Saccharomyces cerevisiae as a His-tagged protein, purified and characterized [Hilditch07].
A putative ortholog of this gene was identified in Aspergillus niger, designated GAAC [MartensUzunova08].
Molecular Weight of Polypeptide: 33.407 kD (from nucleotide sequence)
Enzymatic reaction of: 2-keto-3-deoxy-L-galactonate aldolase
Synonyms: 2-keto-3-deoxy-L-galactonic acid aldolase, L-threo-3-deoxy-hexulosonate aldolase
EC Number: 18.104.22.168
The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the direction of enzyme catalysis.
This reaction is reversible. [Hilditch07]
