| sarcosine/dimethylglycine N-methyltransferase | Cells of the oxygen-evolving halotolerant cyanobacterium Aphanocthece halophytica synthesize betaine from glycine by a three-step methylation process. The first enzyme, EC 2.1.1.156, glycine/sarcosine N-methyltransferase, leads to the formation of either sarcosine or N,N-dimethylglycine, which is further methylated to yield betaine (N,N,N-trimethylglycine) by the action of this enzyme. Both of these enzymes can catalyse the formation of N,N-dimethylglycine from sarcosine. The reactions are strongly inhibited by S-adenosyl-L-homocysteine. Group: Enzymes. Synonyms: ApDMT; sarcosine-dimethylglycine methyltransferase; SDMT; sarcosine dimethylglycine N-methyltransferase; S-adenosyl-L-methionine:N,N-dimethylglycine N-methyltransferase. Enzyme Commission Number: EC 2.1.1.157. 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-1753; sarcosine/dimethylglycine N-methyltransferase; EC 2.1.1.157; ApDMT; sarcosine-dimethylglycine methyltransferase; SDMT; sarcosine dimethylglycine N-methyltransferase; S-adenosyl-L-methionine:N,N-dimethylglycine N-methyltransferase. Cat No: EXWM-1753. |  |
| glycine/sarcosine/dimethylglycine N-methyltransferase | Unlike EC 2.1.1.156 (glycine/sarcosine N-methyltransferase), EC 2.1.1.157 (sarcosine/dimethylglycine N-methyltransferase) and EC 2.1.1.161 (dimethylglycine N-methyltransferase), this enzyme, from the halophilic methanoarchaeon Methanohalophilus portucalensis, can methylate glycine and all of its intermediates to form the compatible solute betaine. Group: Enzymes. Synonyms: GSDMT; glycine sarcosine dimethylglycine N-methyltransferase. Enzyme Commission Number: EC 2.1.1.162. 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-1759; glycine/sarcosine/dimethylglycine N-methyltransferase; EC 2.1.1.162; GSDMT; glycine sarcosine dimethylglycine N-methyltransferase. Cat No: EXWM-1759. | |
| betaine-aldehyde dehydrogenase | In many bacteria, plants and animals, the osmoprotectant betaine is synthesized in two steps: (1) choline to betaine aldehyde and (2) betaine aldehyde to betaine. This enzyme is involved in the second step and appears to be the same in plants, animals and bacteria. In contrast, different enzymes are involved in the first reaction. In plants, this reaction is catalysed by EC 1.14.15.7 (choline monooxygenase), whereas in animals and many bacteria it is catalysed by either membrane-bound EC 1.1.99.1 (choline dehydrogenase) or soluble EC 1.1.3.17 (choline oxidase). In some bacteria, betaine is synthesized from glycine through the actions of EC 2.1.1.156 (glycine/sarcosine N-methyltransferase) and EC 2.1.1.157 (sarcosine/dimethylglycine N-methyltransferase). Group: Enzymes. Synonyms: betaine aldehyde oxidase; BADH; betaine aldehyde dehydrogenase; BetB. Enzyme Commission Number: EC 1.2.1.8. CAS No. 9028-90-4. 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-1182; betaine-aldehyde dehydrogenase; EC 1.2.1.8; 9028-90-4; betaine aldehyde oxidase; BADH; betaine aldehyde dehydrogenase; BetB. Cat No: EXWM-1182. | |
| choline monooxygenase | The spinach enzyme, which is located in the chloroplast, contains a Rieske-type [2Fe-2S] cluster, and probably also a mononuclear Fe centre. Requires Mg2+. Catalyses the first step of glycine betaine synthesis. In many bacteria, plants and animals, betaine is synthesized in two steps: (1) choline to betaine aldehyde and (2) betaine aldehyde to betaine. Different enzymes are involved in the first reaction. In plants, the reaction is catalysed by this enzyme whereas in animals and many bacteria it is catalysed by either membrane-bound EC 1.1.99.1 (choline dehydrogenase) or soluble EC 1.1.3.17 (choline oxidase). The enzyme involved in the second step, EC 1.2.1.8 (betaine-aldehyde dehydrogenase), appears to be the same in plants, animals and bacteria. In some bacteria, betaine is synthesized from glycine through the actions of EC 2.1.1.156 (glycine/sarcosine N-methyltransferase) and EC 2.1.1.157 (sarcosine/dimethylglycine N-methyltransferase). Group: Enzymes. Enzyme Commission Number: EC 1.14.15.7. CAS No. 118390-76-4. 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-0950; choline monooxygenase; EC 1.14.15.7; 118390-76-4. Cat No: EXWM-0950. | |
| dimethylglycine N-methyltransferase | This enzyme, from the marine cyanobacterium Synechococcus sp. WH8102, differs from EC 2.1.1.157, sarcosine/dimethylglycine N-methyltransferase in that it cannot use sarcosine as an alternative substrate. Betaine is a 'compatible solute' that enables cyanobacteria to cope with osmotic stress by maintaining a positive cellular turgor. Group: Enzymes. Synonyms: BsmB; DMT. Enzyme Commission Number: EC 2.1.1.161. 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-1758; dimethylglycine N-methyltransferase; EC 2.1.1.161; BsmB; DMT. Cat No: EXWM-1758. | |

Differs from EC 2.1.1.20, glycine N-methyltransferase, as it can further methylate the product of the first reaction. Acetate, dimethylglycine and S-adenosyl-L-homocysteine can inhibit the reaction. Group: Enzymes. Synonyms: ApGSMT; glycine-sarcosine methyltransferase; GSMT; GMT; glycine sarcosine N-methyltransferase; S-adenosyl-L-methionine:sarcosine N-methyltransferase. Enzyme Commission Number: EC 2.1.1.156. CAS No. 294210-82-5. 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.
