Pyruvatoxime
Synthetic dimer was found to react rapidly with pyruvate to form the expected oxime. 1H NMR spectrum of the purified oxime is superimposable with that arising when the dimer and pyruvate are mixed and the spectrum taken immediately thereafter. Then the mass spectrum of the reaction product of cycloserine dimer and methylpyruvate is totally consistent with the formation of a stable oxime derivative. Furthermore, when cycloserine is incubated with pyruvate the oxime derived from the dimer is found.(PMID: 2495795) [HMDB] Synthetic dimer was found to react rapidly with pyruvate to form the expected oxime. 1H NMR spectrum of the purified oxime is superimposable with that arising when the dimer and pyruvate are mixed and the spectrum taken immediately thereafter.

3-Oxoalanine
Human lysosomal arylsulfate A (ASA) is a member of the sulfatase family which requires the posttranslational oxidation of thiol group of a cysteine that is conserved among all eukaryotic sulfatases, yielding 2-formylglycine.
