| 11. | This pyridoxal-phosphate protein is activated by divalent metal cations ( e . g.
|
| 12. | The P protein binds the alpha-amino group of glycine through its pyridoxal phosphate cofactor.
|
| 13. | They are natural toxins that cause slow binding inhibition by interfering with the coenzyme pyridoxal phosphate.
|
| 14. | The pyridoxal phosphate cofactor binds lysine 69 at the C-terminus end of the barrel domain.
|
| 15. | The toxins react with pyridoxal 5-phosphate the activated form of pyridoxine and form a hydrazone.
|
| 16. | The protein encoded by this gene is a class III pyridoxal-phosphate-dependent amino donor.
|
| 17. | Lysine 69 on ornithine decarboxylase ( ODC ) binds the cofactor pyridoxal phosphate to form a Schiff base.
|
| 18. | The active enzyme is a homodimer of 50-kD subunits complexed to pyridoxal-5-phosphate.
|
| 19. | Propargylglycine and ?-cyanoalanine are two sterically hinders the active site, blocking cysteine from attacking pyridoxal phosphate.
|
| 20. | This intermediate ( 5-HTP ) is decarboxylated by pyridoxal phosphate and 5-hydroxytryptophan decarboxylase to produce serotonin.
