Activating Compound

EC Number Activating Compound Comment Organism Structure
2.7.1.19 dithiothreitol in light-adapted extracts, the presence or absence of reduced dithiothreitol has no significant effect on enzyme activity. However, the dark-adapted extracts incubated with reduced dithiothreitol exhibit a highly significant increase in enzyme activity Vaucheria litorea

Inhibitors

EC Number Inhibitors Comment Organism Structure
2.7.1.19 dithiothreitol light- and dark-adapted extract prepared and assayed without reducing agent, is not significantly affected by incubation with reduced dithiothreitol, however, subsequent incubation with oxidized dithiothreitol results in a significant reduction of enzyme activity under both light and dark conditions Elysia chlorotica

Expression

EC Number Organism Comment Expression
2.7.1.19 Elysia chlorotica prk transcript levels decrease upon illumination (13.4fold by 2 h post-illumination) and by 1.5fold after 2 h dark. Enzyme activity decreases with increasing starvation time, though activity is still measureable after 6 months down
2.7.1.19 Vaucheria litorea maximum expression of prk transcript is detected 6 h postillumination with 78.6fold increases. 2 h into the 12 h dark cycle, prk transcript level is still elevated 31.2fold up
