Catalysis of the reaction: L-homoserine + NADP+ = L-aspartate-4-semialdehyde + NADPH + H+.

major histocompatibility complex class II biosynthesis

The formation from simpler components of major histocompatibility protein class II.

Catalysis of the reaction: ATP + L-homoserine = ADP + O-phospho-L-homoserine.

regulation of major histocompatibility complex class I biosynthesis

Any process that modulates the frequency, rate or extent of the formation from simpler components of MHC class I.

Catalysis of the reaction: acetyl-CoA + L-homoserine = CoA + O-acetyl-L-homoserine.

Catalysis of the random hydrolysis of 1,4-linkages between N-acetyl-beta-D-glucosamine and D-glucuronate residues in hyaluronate.

positive regulation of MHC class I biosynthesis

positive regulation of major histocompatibility complex class I biosynthesis
