DOI: 10.1002/pro.4131
Abstract: Aldehyde dehydrogenase 4A1 (ALDH4A1) catalyzes the final steps of both proline and hydroxyproline catabolism. It is a dual substrate enzyme that catalyzes the NAD+‐dependent oxidations of L‐glutamate‐γ‐semialdehyde to L‐glutamate (proline metabolism), and 4‐hydroxy‐L‐glutamate‐γ‐semialdehyde to 4‐erythro‐hydroxy‐L‐glutamate… read more here.

DOI: 10.1080/21655979.2019.1600966
Abstract: ABSTRACT Trans-4-hydroxy-L-proline (Hyp) production by Escherichia coli (E. coli) in fermentation is a high-oxygen-demand process. E. coli secretes large amounts of soluble protein, especially in the anaphase of fermentation, which is an important factor leading… read more here.

DOI: 10.2210/pdb6r77/pdb
Abstract: Abstract Hydroxyprolines (Hyp) are non-standard amino acids derived from the post-translational modification of proteins by prolyl hydroxylase enzymes. Some plants and bacteria produce Hyp, and the isomers trans-3-Hydroxy- l -proline (T3LHyp) and trans-4-Hydroxy- l -proline… read more here.
