Cystathionine ketimine
D-cystathionine ketimine and L-cystathionine ketimine enhance superoxide generation by human neutrophils in a different manner. D-Cystathionine Ketimine enhanced seryl phosphorylation of 16. 5-kDa protein in human neutrophils, while L-Cystathionine Ketimine enhanced tyrosyl phosphorylation of 45-kDa protein.(PMID: 10049498). Among the cystathionine metabolites, cystathionine ketimine and N-acetyl-S-(3-oxo-3-carboxy-n-propyl) cysteine (NAc-OCPC) significantly enhanced the N-formylmethionylleucylphenylalanine (fMLP)-induced superoxide generation, but cystathionine, NAc-cystathionine, and cyclothionine did not enhance the superoxide generation. Cystathionine ketimine and NAc-OCPC also enhanced superoxide generation induced by opsonized zymosan (OZ) but not that induced by arachidonic acid (AA) and phorbol 12-myristate 13-acetate (PMA). Superoxide generation induced by cystathionine ketimine and NAc-OCPC was inhibited by genistein, an inhibitor of tyrosine kinase, and was enhanced by 1-(5-isoquinoline sulfonyl)-2-methylpiperazine (H-7), an inhibitor of protein kinase C.(PMID: 10708546) [HMDB] Cystathionine ketimine (CT) is a cyclic amino acid that was found to have a priming effect on superoxide generation in human neutrophils (PMID: 10708546). D-Cystathionine ketimine and L-cystathionine ketimine enhance superoxide generation by human neutrophils in two different manners. D-Cystathionine ketimine enhanced seryl phosphorylation of 16.5-kDa protein in human neutrophils, while L-cystathionine ketimine enhanced tyrosyl phosphorylation of 45-kDa protein (PMID: 10049498). Cystathionine ketimine was found in the urine of a cystathioninuria patient (PMID: 8373176).
