In enzymology, a N6-hydroxylysine O-acetyltransferase () is an enzyme that catalyzes the chemical reaction acetyl-CoA + N6-hydroxy-L-lysine CoA + N6-acetyl-N6-hydroxy-L-lysine Thus, the two substrates of this enzyme are acetyl-CoA and N6-hydroxy-L-lysine, whereas its two products are CoA and N6-acetyl-N6-hydroxy-L-lysine. This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. The systematic name of this enzyme class is acetyl-CoA:N6-hydroxy-L-lysine 6-acetyltransferase. Other names in common use include N6-hydroxylysine:acetyl CoA N6-transacetylase, N6-hydroxylysine acetylase, and acetyl-CoA:6-N-hydroxy-L-lysine 6-acetyltransferase. This enzyme participates in lysine degradation. References EC 2.3.1 Enzymes of unknown structure
