Studies on lipoamidase: characterization of the enzyme in human serum and breast milk.

Lipoamidase activity was detected in human serum with both lipoyllysine (epsilon-N-(DL-lipoyl)-L-Lysine) and lipoylPABA (N-DL-lipoyl-p-aminobenzoate) as substrates, whereas lipoamidase in human milk used lipoylPABA, but not lipoyllysine as substrate. This suggested that lipoamidase activities in serum and milk are due to different enzymes. Studies with… CONTINUE READING
