ID 2.3.2.37 DE ergosteryl-3beta-O-L-aspartate synthase. CA ergosterol + L-aspartyl-tRNA(Asp) = 1-(ergostan-3beta-yl)-L-aspartate + CA tRNA(Asp). CC -!- The enzyme, detected in fungal species that belong to the Ascomycota CC and Basidiomycota phyla and characterized from Aspergillus fumigatus, CC is bifunctional. CC -!- The AspRS domain catalyzes the transfer of L-aspartate to tRNA(Asp) CC (EC 6.1.1.12), while the second domain carries out the transfer of CC L-aspartate to the 3beta-hydroxyl of ergosterol. //
