Is threonine an essential amino acid for birds?

Abstract

Amino acid threonine is known not to be synthesized in the vertebrates. However, as far as birds are concerned, the main enzyme which is responsible for threonine degradation is threonine dehydrogenase. Thus, this paper pays special attention to threonine dehydrogenase to establish its inability to synthesize threonine due to reversibility of the reaction of threonine degradation. It shows why threonine dehydrogenase in the bird tissues can not be involved in the biosynthesis of threonine.
