BiosynthesisofProlineinBacteria
Among the twenty amino acids encoded by the genetic code, proline is unique in having a cyclic structure with its side chain connected to the amino group to create a secondary amine. As a consequence of its cyclic structure, proline constrains the structure of proteins where it occurs, disrupting alpha-helices. Isomerization between the cis and trans forms of proline in proteins is isomerized by peptidyl-prolyl isome......阅读全文
