Describe each enzyme w/ group and important information presented?
- Amylase: Jodi and co (linking arms group)
- specific and general acid/base
- Citrate synthase:
- general acid/base
- glutamine synthase: Unicorn group
- Glutamate is P'd, but is ultimately removed to form Glutamine
- hexosaminidase A (hex a):
- General and specific acid/base
- Urease: The Dusos (muggers)
- Metal catalyzed, and general Acid/base
What is the mechanism for the enzyme that your group presented. Give a detailed answer, including important chemical structures.
- Enzyme binds ATP and galactose
- Asp186 (-) removes proton from OH on C-1
- Newly nucleophilic O- on C-1 attacks Pi
- ADP and G-1-P released
- Asp186 releases H due to pKa
