Leukotriene A4 hydrolase (LTA4H) is a monomeric, soluble enzyme that uses a Zn2+ cofactor to catalyse the hydrolysis of the allylic epoxide leukotriene A4 (LTA4) (McGee & Fitzpatrick 1985). LTA4H can also catalyse the hydrolysis of 4S(5)-epoxy-17(S)-hydroxydocosahexaenoic acid (4S(5)-epoxy-17(S)-HDHA) to the trihydroxydocosahexaenoic acids 4(S), 11(R), 17(S)-triHDHA and 4(S), 5(R), 17(S)-triHDHA (RvD3 and RvD4 respectively) (Dalli et al. 2013, Serhan et al. 2002, Winkler et al. 2013, 2016). The D-resolvins are anti-inflammatory, pro-resolving, and non-phlogistic (that is, they mediate the clearance of leukocytes without eliciting an inflammatory response) (Serhan et al. 2008).
