| Fmoc-Sec(pMeOBzl)-OH | Building block for the introduction of selenocysteine during Fmoc SPPS. Selenocysteine derivatives can undergo enantiomerization during coupling and can form dehydroalanine and β-piperidinylalanine containing side products during subsequent chain elongation. Therefore, activation methods, such as HBTU or PyBOP which involve the addition of a tertiary, base should be avoided for addition of the Sec and all subsequent residues. Cleavage and side-chain deprotection of Sec-containing peptides can be effected using tFA-m-cresol-thioanisole-EDT-water (80:5:5:5:5) or TFA-water-DCM-TIS (89:5:51) at 4 °C. As the Se-pMeOBzl bond is stable to TFA, these methods result in the formation of the corresponding Sev(pMeOBzl) peptide. Peptides containing two Sec(pMeOBzl) residues can be oxidized directly to the corresponding selenocystinyl peptides by treatment with 5-10% DMSO in TFA. Uses: Peptide synthesis. Group: Amino acids.

| sarcosine reductase | The reaction is observed only in the direction of sarcosine reduction. The enzyme from Eubacterium acidaminophilum consists of subunits A, B and C. Subunit B contains selenocysteine and a pyruvoyl group, and is responsible for sarcosine binding and methylamine release. Subunit A, which also contains selenocysteine, is reduced by thioredoxin, and is needed to convert the carboxymethyl group into a ketene equivalent, in turn used by subunit C to produce acetyl phosphate. Only subunit B distinguishes this enzyme from EC 1.21.4.2 (glycine reductase) and EC 1.21.4.4 (betaine reductase). Group: Enzymes. Enzyme Commission Number: EC 1.21.4.3. CAS No. 125752-88-7. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-1258; sarcosine reductase; EC 1.21.4.3; 125752-88-7. Cat No: EXWM-1258. | |
