Organism

Homo sapiens (Human) [Complete proteome]

Taxonomic identifier

9606 [NCBI]

Taxonomic lineage

Eukaryota › Metazoa › Chordata › Craniata › Vertebrata › Euteleostomi › Mammalia › Eutheria › Euarchontoglires › Primates › Haplorrhini › Catarrhini › Hominidae › Homo

Protein attributes

Sequence length	340 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Cofactor	Binds 1 magnesium ion per subunit By similarity.
Subcellular location	Mitochondrion Potential.
Sequence similarities	Belongs to the hpcH/hpaI aldolase family. Citrate lyase beta subunit-like subfamily.
Caution	This organism lacks the other subunits that are necessary for ATP-independent citrate lyase activity. Even though this protein has clear similarity to citrate lyase beta subunit, it is expected to have a somewhat different enzyme activity.
