Identification of two additional members of the membrane-bound dipeptidase family.
Habib G.M., Shi Z.-Z., Cuevas A.A., Lieberman M.W.
We have cloned two mouse cDNAs encoding previously unidentified membrane-bound dipeptidases [membrane-bound dipeptidase-2 (MBD-2) and membrane-bound dipeptidase-3 (MBD-3)] from membrane-bound dipeptidase-1 (MBD-1) deficient mice (Habib, G.M., Shi, Z-Z., Cuevas, A.A., Guo, Q., Matzuk, M.M., and Lie ... >> More
We have cloned two mouse cDNAs encoding previously unidentified membrane-bound dipeptidases [membrane-bound dipeptidase-2 (MBD-2) and membrane-bound dipeptidase-3 (MBD-3)] from membrane-bound dipeptidase-1 (MBD-1) deficient mice (Habib, G.M., Shi, Z-Z., Cuevas, A.A., Guo, Q., Matzuk, M.M., and Lieberman, M.W. (1998) Proc. Natl. Acad. Sci. USA 95, 4859-4863). These enzymes are closely related to MBD-1 (EC 3.4.13.19), which is known to cleave leukotriene D4 (LTD4) and cystinyl-bis-glycine. MBD-2 cDNA is 56% identical to MBD-1 with a predicted amino acid identity of 33%. The MBD-3 and MBD-1 cDNAs share a 55% nucleotide identity and a 39% predicted amino acid sequence identity. All three genes are tightly linked on the same chromosome. Expression of MBD-2 and MBD-3 in Cos cells indicated that both are membrane-bound through a glycosylphosphatidyl-inositol linkage. MBD-2 cleaves leukotriene D4 (LTD4) but not cystinyl-bis-glycine, while MBD-3 cleaves cystinyl-bis-glycine but not LTD4. MBD-1 is expressed at highest levels in kidney, lung, and heart and is absent in spleen, while MBD-2 is expressed at highest levels in lung, heart, and testis and at somewhat lower levels in spleen. Of the tissues examined, MBD-3 expression was detected only in testis. Our identification of a second enzyme capable of cleaving LTD4 raises the possibility that clearance of LTD4 during asthma and in related inflammatory conditions may be mediated by more than one enzyme. << Less

Purification and characterization of human microsomal dipeptidase.
Adachi H., Kubota I., Okamura N., Iwata H., Tsujimoto M., Nakazato H., Nishihara T., Noguchi T.

Human microsomal dipeptidase (MDP, formerly referred to as dehydropeptidase-I or renal dipeptidase) [EC 3.4.13.11] was solubilized from the membrane fraction of kidney by treatment with octyl-beta-D-glucoside and purified by a procedure including ion exchange chromatography and affinity chromatography on cilastatin-immobilized Sepharose. The purified human MDP was found to be homogeneous on sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis. The apparent molecular weight (Mr) was estimated by SDS-polyacrylamide gel electrophoresis under non-reducing conditions to be 130 kDa, comprising a homodimer of two subunits. After treatment with endoglycosidase F, human MDP showed a single band with an apparent Mr of 42 kDa on SDS-polyacrylamide gel electrophoresis. Human MDP was found to bind to Con A-Sepharose and the activity was eluted with methyl-alpha-D-mannopyranoside, suggesting that human MDP is a glycoprotein. We also examined the substrate specificity of human MDP and found that human MDP catalyzed the hydrolysis of S(substituent)-L-cysteinyl-glycine adducts such as L-cystinyl-bis(glycine) and S-N-ethylmaleimide-L-cysteinyl-glycine, as well as the conversion of leukotriene D4 to leukotriene E4. These results suggest that MDP might play an important role in the metabolism of glutathione and leukotriene. << Less
