| dCTP deaminase (dUMP-forming) | Requires Mg2+. Is highly specific for dCTP as substrate as dCMP, CTP, CDP, CMP, cytosine or deoxycytosine are not deaminated. While most bacteria require two enzymes to form dUMP from dCTP (EC 3.5.4.13, dCTP deaminase and EC 3.6.1.23, dUTP diphosphatase), the archaeon Methanocaldococcus jannaschii uses a single enzyme to carry out both functions. This enzyme can also act as a dUTP diphosphatase, but more slowly. Group: Enzymes. Enzyme Commission Number: EC 3.5.4.30. 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-4558; dCTP deaminase (dUMP-forming); EC 3.5.4.30. Cat No: EXWM-4558. | |
| L-2-hydroxycarboxylate dehydrogenase (NAD+) | The enzyme from the archaeon Methanocaldococcus jannaschii acts on multiple (S)-2-hydroxycarboxylates including (2R)-3-sulfolactate, (S)-malate, (S)-lactate, and (S)-2-hydroxyglutarate. Note that (2R)-3-sulfolactate has the same stereo configuration as (2S)-2-hydroxycarboxylates. Group: Enzymes. Synonyms: (R)-sulfolactate:NAD+ oxidoreductase; L-sulfolactate dehydrogenase; (R)-sulfolactate dehydrogenase; L-2-hydroxyacid dehydrogenase (NAD+); ComC. Enzyme Commission Number: EC 1.1.1.337. CAS No. 81210-65-3. 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-0251; L-2-hydroxycarboxylate dehydrogenase (NAD+); EC 1.1.1.337; 81210-65-3; (R)-sulfolactate:NAD+ oxidoreductase; L-sulfolactate dehydrogenase; (R)-sulfolactate dehydrogenase; L-2-hydroxyacid dehydrogenase (NAD+); ComC. Cat No: EXWM-0251. | |
| L-2-hydroxycarboxylate dehydrogenase [NAD(P)+] | The enzyme from the archaeon Methanocaldococcus jannaschii catalyses the reversible oxidation of (2R)-3-sulfolactate and (S)-malate to 3-sulfopyruvate and oxaloacetate, respectively (note that (2R)-3-sulfolactate has the same stereochemical configuration as (2S)-2-hydroxycarboxylates). The enzyme can use both NADH and NADPH, although activity is higher with NADPH. The oxidation of (2R)-3-sulfolactate was observed only in the presence of NADP+. The same organism also possesses an NAD+-specific enzyme with similar activity, cf. EC 1.1.1.337, L-2-hydroxycarboxylate dehydrogenase (NAD+). Group: Enzymes. Synonyms: MdhII; lactate/malate dehydrogenase. Enzyme Commission Number: EC 1.1.1.375. 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-0293; L-2-hydroxycarboxylate dehydrogenase [NAD(P)+]; EC 1.1.1.375; MdhII; lactate/malate dehydrogenase. Cat No: EXWM-0293. | |
| L-cysteine desulfidase | The enzyme from the archaeon Methanocaldococcus jannaschii contains a [4Fe-4S] cluster and is specific for L-cysteine (cf. EC 4.4.1.1, cystathionine γ-lyase). It cleaves a carbon-sulfur bond releasing sulfide and the unstable enamine product 2-aminoprop-2-enoate that tautomerizes to an imine form, which undergoes a hydrolytic deamination to form pyruvate and ammonia. The same reaction can also be catalysed by some pyridoxal-phosphate proteins (cf. EC 4.4.1.1, cystathionine γ-lyase). Group: Enzymes. Synonyms: L-cysteine desulfhydrase. Enzyme Commission Number: EC 4.4.1.28. 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-5330; L-cysteine desulfidase; EC 4.4.1.28; L-cysteine desulfhydrase. Cat No: EXWM-5330. | |
