The esterification of alcohols with fatty acids is a universal mechanism to form inert storage forms of sterols, di- and triacylglycerols, and retinoids. In ocular tissues, formation of retinyl esters is an essential step in the enzymatic regeneration of the visual chromophore (11-<i>cis</i>-retinal). Acyl-CoA wax alcohol acyltransferase 2 (AWAT2), also known as multifunctional <i>O</i>-acyltransferase (MFAT), is an integral membrane enzyme with a broad substrate specificity that has been shown to preferentially esterify 11-<i>cis</i>-retinol and thus contribute to formation of a readily available pool of <i>cis</i> retinoids in the eye. However, the mechanism by which this promiscuous enzyme can gain substrate specificity is unknown. Here, we provide evidence for an allosteric modulation of the enzymatic activity by 11-<i>cis</i> retinoids. This regulation is independent from cellular retinaldehyde-binding protein (CRALBP), the major <i>cis</i>-retinoid binding protein. This positive-feedback regulation leads to decreased esterification rates for 9-<i>cis</i>, 13-<i>cis</i>, or all-<i>trans</i> retinols and thus enables preferential synthesis of 11-<i>cis</i>-retinyl esters. Finally, electron microscopy analyses of the purified enzyme indicate that this allosteric effect does not result from formation of functional oligomers. Altogether, these data provide the experimental basis for understanding regulation of AWAT2 substrate specificity. << Less
