| D-Hydantoinase (Crude Enzyme) | This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in cyclic amides. This enzyme participates in 3 metabolic pathways: pyrimidine metabolism,beta-alanine metabolism, and pantothenate and coa biosynthesis. This product with the indicated enzyme activity was briefly purified from engineered E. coli. Applications: Medicine; synthesis; nutrition. Group: Enzymes. Synonyms: hydantoinase; hydropyrimidine hydrase; hydantoin peptidase; pyrimidine hydrase; dihydropyrimidinase. Enzyme Commission Number: EC 3.5.2.2. CAS No. 9030-74-4. Activity: Undetermined. Appearance: Clear to translucent yellow solution. Storage: at -20 °C or lower, for at least 1 month. Source: E. coli. hydantoinase; hydropyrimidine hydrase; hydantoin peptidase; pyrimidine hydrase; dihydropyrimidinase. Pack: 100ml. Cat No: NATE-1838. |  |
| dihydropyrimidinase | Also acts on dihydrothymine and hydantoin. Group: Enzymes. Synonyms: hydantoinase; hydropyrimidine hydrase; hydantoin peptidase; pyrimidine hydrase; D-hydantoinase. Enzyme Commission Number: EC 3.5.2.2. CAS No. 9030-74-4. 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-4503; dihydropyrimidinase; EC 3.5.2.2; 9030-74-4; hydantoinase; hydropyrimidine hydrase; hydantoin peptidase; pyrimidine hydrase; D-hydantoinase. Cat No: EXWM-4503. | |
| hydantoin racemase | This enzyme, along with N-carbamoylase (EC 3.5.1.77 and EC 3.5.1.87) and hydantoinase, forms part of the reaction cascade known as the "hydantoinase process", which allows the total conversion of D,L-5-monosubstituted hydantoins into optically pure D- or L-amino acids. The enzyme from Pseudomonas sp. (HyuE) has a preference for hydantoins with aliphatic substituents, e.g. D- and L-5-(2-methylthioethyl)hydantoin, whereas that from Arthrobacter aurescens shows highest activity with arylalkyl substituents, especially 5-benzylhydantoin, at the 5-position. In the enzyme from Sinorhizobium meliloti, Cys76 is responsible for recognition and proton retrieval of D-isomers, while Cys181 is responsible for L-isomer recognition and racemization. Group: Enzymes. Synonyms: 5'-monosubstituted-hydantoin racemase; HyuA; HyuE. Enzyme Commission Number: EC 5.1.99.5. 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. EXWM-5437; hydantoin racemase; EC 5.1.99.5; 5'-monosubstituted-hydantoin racemase; HyuA; HyuE. Cat No: EXWM-5437. | |
| N-carbamoyl-D-amino-acid hydrolase | This enzyme, along with EC 3.5.1.87 (N-carbamoyl-L-amino-acid hydrolase), EC 5.1.99.5 (hydantoin racemase) and hydantoinase, forms part of the reaction cascade known as the "hydantoinase process", which allows the total conversion of D,L-5-monosubstituted hydantoins into optically pure D- or L-amino acids. It has strict stereospecificity for N-carbamoyl-D-amino acids and does not act upon the corresponding L-amino acids or on the N-formyl amino acids, N-carbamoyl-sarcosine, -citrulline, -allantoin and -ureidopropanoate, which are substrates for other amidohydrolases. Group: Enzymes. Synonyms: D-N-carbamoylase; N-carbamoylase (ambiguous); N-carbamoyl-D-amino acid hydrolase. Enzyme Commission Number: EC 3.5.1.77. CAS No. 71768-08-6. 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-4468; N-carbamoyl-D-amino-acid hydrolase; EC 3.5.1.77; 71768-08-6; D-N-carbamoylase; N-carbamoylase (ambiguous); N-carbamoyl-D-amino acid hydrolase. Cat No: EXWM-4468. | |
| N-carbamoyl-L-amino-acid hydrolase | This enzyme, along with EC 3.5.1.77 (N-carbamoyl-D-amino-acid hydrolase), EC 5.1.99.5 (hydantoin racemase) and hydantoinase, forms part of the reaction cascade known as the "hydantoinase process", which allows the total conversion of D,L-5-monosubstituted hydantoins into optically pure D- or L-amino acids. The enzyme from Alcaligenes xylosoxidans has broad specificity for carbamoyl-L-amino acids, although it is inactive on the carbamoyl derivatives of glutamate, aspartate, arginine, tyrosine or tryptophan. The enzyme from Sinorhizobium meliloti requires a divalent cation for activity and can hydrolyse N-carbamoyl-L-tryptophan as well as N-carbamoyl L-amino acids with aliphatic substituents. The enzymeis inactive on derivatives of D-amino acids. In addition to N-carbamoyl L-amino acids, the enzyme can also hydrolyse formyl and acetyl derivatives to varying degrees. Group: Enzymes. Synonyms: N-carbamyl L-amino acid amidohydrolase; N-carbamoyl-L-amino acid amidohydrolase; L-N-car. Enzyme Commission Number: EC 3.5.1.87. 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-4478; N-carbamoyl-L-amino-acid hydrolase; EC 3.5.1.87; N-carbamyl L-amino acid amidohydrolase; N-carbamoyl-L-amino acid amidohydrolase; L-N-carbamoylase; N-carbamoylase (ambiguous). Cat No: EXWM-4478. | |
