Purification of membrane-bound aminopeptidase from rat brain: Identification of aminopeptidase M

Abstract

Two different membrane-bound aminopeptidases were isolated from rat brain membranes, one with a puromycin sensitive activity and the other, not affected by 10 μM puromycin. The physicochemical, catalytic and immunological properties of the latter were compared to those of aminopeptidase M purified from rat kidney membranes and allowed us to conclude to large similarities between these two enzymes.

Because the two brain aminopeptidases were both sensitive to bestatin, it remains to be established whether both or only aminopeptidase M is involved in endogenous enkephalin inactivation.

    Hence, the addition of metal chelators such as EDTA and 1,10-phenanthroline inhibited their activity (Table 3). It was also found that the antibiotic puromycin, which is used to distinguish between cytosolic alanyl APs and membrane bound APs (Gros et al., 1985), inhibited AP1 and AP2, implying that the two enzymes may indeed be cytosolic APs. The two APs were found to have similar inhibition constants for all the inhibitors tested.

    APN can preferentially release neutral or basic amino acids from the N-terminal of unsubstituted oligopeptides, amides and arylamide, with the exception of peptides with Pro in the penultimate position.3 APN is widely distributed in most of mammalian tissues such as kidney,4 intestine,5 liver,6 lung,7 brain,8 fibroblasts,9 vessels of smooth muscle,10 haematopoietic system,11 and so on. The widely distribution of APN associated with its broad substrate specificity suggests that APN has probably several physiological functions, such as protein modification, activation, and degradation as well as in the metabolism of biologically active peptides in tumor metastasis and leukemia.12,13

    Indeed, human PSA is completely inhibited by 100 μm puromycin (56), and IC50 values are reported to be of the order of 1 μm (57). In this respect, PAM-1 is more like aminopeptidase N (Ki ∼ 100 μm) (58). However, we cannot exclude the possibility that the N-terminal tag present on the recombinant nematode enzyme is influencing binding of puromycin, even though it appears not to affect interactions with the other inhibitors tested.
