fish amylase vs amylase from the small intestines

Postby Tiamaria » Fri Jan 14, 2011 5:29 pm

Greetings!

I'm working on a project that asks if amylase were isolated from any 2 organisms, would it show the same temperature optimum?

I answered yes because i understand that amylase works best at around 37 degrees celcius, but I dont know how to explain my answer further. Does anyone have any suggestions?

The amylase you have used works best at 37ºC, but is it universally true?
What do you know of temperature regulation in different animals? (is there any? How does it work?...)
So what is the average temperature of a fish? a Bacteria? a human? a snake?
What is the consequence on the optimal temperature of function for their enzyme?

well, let's say, that if it had optima at 37°C, the fish living in water of ~4-10°C would have amylase working only for about 10%. Do you think, such a fish would prosper?

Cis or trans? That's what matters.
