Manual Audit:BIOCAD_RXN-85535

Transamination of acetoin using an amino donor (e.g., L-glutamate) to produce 3-amino-2-butanone (aminoacetoin). This step introduces the nitrogen atom required for the pyrazine ring.

Aminoacetoin Formation

Acetoin[C4H8O2] + L-Glutamate[C5H9NO4] = 3-Amino-2-butanone[C4H9NO] + 2-Oxoglutarate[C5H6O5]
