Enzymes

General function:
Involved in pyridoxal kinase activity
Specific function:
Phosphorylates B6 vitamers; functions in a salvage pathway. Uses pyridoxamine, but has negligible activity toward pyridoxal and pyridoxine as substrates
Gene Name:
pdxY
Locus Tag:
PA5516
Molecular weight:
31.3 kDa
Reactions
ATP + pyridoxal = ADP + pyridoxal 5'-phosphate.
General function:
Coenzyme transport and metabolism
Specific function:
Catalyzes the oxidation of either pyridoxine 5'- phosphate (PNP) or pyridoxamine 5'-phosphate (PMP) into pyridoxal 5'-phosphate (PLP)
Gene Name:
pdxH
Locus Tag:
PA1049
Molecular weight:
24.9 kDa
Reactions
Pyridoxamine 5'-phosphate + H(2)O + O(2) = pyridoxal 5'-phosphate + NH(3) + H(2)O(2).
Pyridoxine 5'-phosphate + O(2) = pyridoxal 5'-phosphate + H(2)O(2).
