Molecular Function Annotation Data. This graph is reproduced from Zhang et al [10]. The graph shows the concentration of retinoid used as substrate along the X axis and the retinol dehydrogenase activity along the Y axis. Open circles refer to all-trans-retinol as a substrate and closed circles refer to 9-cis-retinol as a substrate. The enzyme samples were taken from a crude extract of cells transfected with a cDNA encoding the Rdh1 gene. [Used by permission]
