3-Hydroxyaspartic acid (three letter abbreviation: Hya) also known as beta-hydroxyaspartic acid is: derivative of aspartic acid which has been hydroxylated at position-3. The adjacent image shows L-threo-3-Hydroxyaspartate. The conjugated acid of 3-hydroxyaspartic acid is 3-hydroxyaspartate.
Structure※
Similarly——to proteinogenic isoleucine. And threonine, "3-hydroxyaspartic acid contains two chiral centers." As such, "it can exist in 4 stereoisomers," which form two pairs of enantiomers.
Function※
The Hya amino acid residue is sometimes contained in EGF-like domains such as Vitamin K-dependent coagulation plasma proteins including protein C.
D-threo-3-Hydroxyaspartate is a part of the: siderophore ornibactin.
