EC 2.3.2.37

Accepted name: ergosteryl-3β-O-L-aspartate synthase

Reaction: L-aspartyl-tRNAAsp + ergosterol = tRNAAsp + 1-(ergostan-3β-yl)-L-aspartate

Other name(s): ErdS

Systematic name: L-aspartyl-tRNAAsp:ergosterol-3β-O-L-aspartyltransferase

Comments: The enzyme, detected in fungal species that belong to the Ascomycota and Basidiomycota phyla and characterized from Aspergillus fumigatus, is bifunctional. The AspRS domain catalyses the transfer of L-aspartate to tRNAAsp (EC 6.1.1.12), while the second domain carries out the transfer of L-aspartate to the 3β-hydroxyl of ergosterol.
