acyl-homoserine-lactone acylase
Acyl-homoserine lactones (AHLs) are produced by a number of bacterial species and are used by them to regulate the expression of virulence genes in a process known as quorum-sensing.

Plants or animals capable of degrading AHLs would have a therapeutic advantage in avoiding bacterial infection as they could prevent AHL-signalling and the expression of virulence genes in quorum-sensing bacteria.

chloramphenicol O-acetyltransferase
Chloramphenicol acetyltransferase (or CAT) is a bacterial enzyme (EC 2.3.1.28) that detoxifies the antibiotic chloramphenicol and is responsible for chloramphenicol resistance in bacteria. This enzyme covalently attaches an acetyl group from acetyl-CoA to chloramphenicol, which prevents chloramphenicol from binding to ribosomes. A histidine residue, located in the C-terminal section of the enzyme, plays a central role in its catalytic mechanism. Group: Enzymes. Synonyms: chloramphenicol acetyltransferase; chloramphenicol acetylase; chloramphenicol transacetylase; CAT I; CAT II; CAT III. Enzyme Commission Number: EC 2.3.1.28. CAS No. 9040-7-7.

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).

Cilastatin Ammonium Salt
Cilastatin Ammonium Salt is the ammonium salt of Cilastatin, which is a dipeptidase inhibitor of renal enzyme dehydropeptidase-I and leukotriene D4 peptidase. It inhibits metabolism of LTD4 to LTE4 and the hydrolysis of β-lactam antibiotics. It reduces toxic accumulation of cyclosporin A in kidney proximal tubule epithelial cells. It can be combined intravenously with imipenem in order to protect it from dehydropeptidase. It suppresses both host and target metabolism of the broad-spectrum antibiotic imipenem, improving its efficacy. It usually confers antibiotic resistance to certain bacteria because itself does not have antibiotic activity. It has nephroprotective effects.

coproporphyrinogen dehydrogenase
This enzyme differs from EC 1.3.3.3, coproporphyrinogen oxidase, by using S-adenosyl-L-methionine (AdoMet) instead of oxygen as oxidant. It occurs mainly in bacteria, whereas eukaryotes use the oxygen-dependent oxidase. The reaction starts by using an electron from the reduced form of the enzyme's [4Fe-4S] cluster to split AdoMet into methionine and the radical 5'-deoxyadenosin-5'-yl. This radical initiates attack on the 2-carboxyethyl groups, leading to their conversion into vinyl groups. This conversion, -?CH-CH2-COO- ? -CH=CH2 + CO2 + e- replaces the electron initially used. Group: Enzymes. Synonyms: oxygen-independent coproporphyrinogen-III oxidase; HemN; coproporphyrinogen III oxidase. Enzyme Commission Number: EC 1.3.98.3. 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.
