WebJan 4, 1992 · The substrate/product ratio of cysteine oxygenase (plasma cysteine/sulphate) was significantly higher in SLE patients than in controls (median [interquartile range] 362 [224-588] vs 65 [44-111]; p less than 0.00001). The alternative pathway of sulphur metabolism, S-methylation, catalysed by thiolmethyltransferase, was … WebThe DDI Methylation Profile evaluates the plasma levels of methionine, cysteine, SAM, SAH, Hcy, adenosine and cystathionine, and provides the important "methylation index," a ration of SAM to SAH. The test results can facilitate appropriate individualized interventions to improve or normalize methionine metabolism and ameliorate or prevent ...
