3 methods for enzyme regulation? | allosteric, covalent modification, and transcriptional regulation |
what groups disrupt conformational change and are important in covalent modification? | kinases and phosphatases |
when pk is phosphorylated, is it active or not? | inactive |
what happens to the insulin receptor and glycogen phosphorylase when they are phosphorylated? | they become active |
what is reponsible for the fight or flight reflex? | glycogen phosphorylase |
protein kinase A is what kind or regulator? | covalent modification |
glycosylation does what to protein groups? | adds a carbohydrate |
to add a protein to a membrane, what should be added? | a fatty acid |
acetylation is important to what regulation? | histone |
amino acid modification examples include: | glycosylation, fatty acid prenylation |
what do matrix metalloproteases do? | enzymes that degrade extracellular matrix proteins |
what is a t.i.m.p.? | tissue inhibitor of metalloproteases |
what is a zymogen? | inactive protein |
