Oh yeah and why… well, because they (the enzymes), probably come from the same ancestor, but have diversified a while ago, so they won’t have identical primary structure, but still it will be pretty similar (but depends on each case)
Okay, thanks. So, they will be slightly different because of differing structure?
I thought that to, but, if they have a different structure, doesn’t that make it a different enzyme? That was what I have been confused about. Also, because the same enzyme from a different source has different optimum pH, temp,etc right?
