Research

The primary focus of my research is on the metabolism of vitamin A (or retinol-you can see its structure in the background) by channel catfish. Currently we are investigating whether catfish have the same types of vitamin A metabolizing enzymes that mammals have. One of the most important enzymes for processing vitamin A is lecithin:retinol acyltransferase or LRAT. This enzyme takes retinol and lecithin and moves a fatty acid from the lecithin onto the retinol, forming a retinyl ester. We have found this (or a similar) enzyme in catfish liver and are currently involved in determining whether it is LRAT. LRAT is also involved in the mammalian visual cycle, so a new project will involve investigating LRAT in the piscine eye.
