Galactose-1-phosphate uridyltransferase (or GALT, G1PUT) is an enzyme (EC 2.7.7.12) responsible for converting ingested galactose to glucose.
Galactose-1-phosphate uridyltransferase (GALT) catalyzes the second step of the Leloir pathway of galactose metabolism, namely:
In biochemistry, a protein dimer is a macromolecular complex or multimer formed by two protein monomers, or single proteins, which are usually non-covalently bound. Many macromolecules, such as proteins or nucleic acids, form dimers. The word dimer has roots meaning "two parts", di- + -mer. A protein dimer is a type of protein quaternary structure.
A protein homodimer is formed by two identical proteins while a protein heterodimer is formed by two different proteins.
