The early studies on chicken embryos revealed that exposition to 4-oxo-L-proline resulted in the explicit increase in 4-hydroxy-L-proline content in their tissues. In 1962, 4-oxo-L-proline reductase, an enzyme responsible for the reduction of 4-oxo-Lproline, was partially purified from rabbit kidneys and characterized biochemically, but only recently
the molecular identity of the enzyme has been unveiled in our laboratory. The present investigation reports the purific...
