Abstract excerpt
N-Methyltryptophan oxidase (MTOX) contains covalently bound FAD. N-Methyltryptophan binds in a cavity above the re face of the flavin ring. Lys259 is located above the opposite, si face. Replacement of Lys259 with Gln, Ala, or Met blocks (>95%) covalent flavin incorporation in vivo. The mutant apoproteins can be reconstituted with FAD. Apparent turnover rates (k(cat,app)) of the reconstituted enzymes are...
