Which essential amino acid is synthesized from aspartate in bacteria such as E. coli, encoded by all the codons starting with AC, and contains a side chain 1-hydroxyethyl group. It is one of two proteinogenic amino acids with two centers of chirality, the other being isoleucine. Its side chains are often hydrogen-bonded, susceptible to numerous post-translational modifications and undergo phosphorylation through the action of a threonine kinase?
