1.Leukotriene A4 hydrolase: abrogation of the peptidase activity by mutation of glutamic acid-296.

Wetterholm A1, Medina JF, R?dmark O, Shapiro R, Haeggstr?m JZ, Vallee BL, Samuelsson B. Proc Natl Acad Sci U S A. 1992 Oct 1;89(19):9141-5.

The metal-binding motif in the sequence of leukotriene A4 (LTA4) (EC 3.3.2.6), a bifunctional zinc metalloenzyme, contains a glutamic acid that is conserved in several zinc hydrolases. To study its role for the two catalytic activities, Glu-296 in mouse leukotriene A4 hydrolase was replaced by a glutamine or alanine residue by site-directed mutagenesis. Wild-type and mutated cDNAs were expressed four or five times in Escherichia coli, and the resulting proteins were purified to apparent homogeneity. With respect to their epoxide hydrolase activities--i.e., the conversion of LTA4 into leukotriene B4--the mutated enzymes [Gln296]LTA4 hydrolase and [Ala296]LTA4 hydrolase exhibited specific activities of 1070 +/- 160 and 90 +/- 30 nmol of LTB4 per mg of protein per min (mean +/- SD; n = 4 or 5), respectively, corresponding to 150% and 15% of unmutated enzyme. In contrast, when the mutated proteins were assayed for peptidase activity toward alanine-4-nitroanilide, they were found to be virtually inactive (less than or equal to 0.
