(−)-limonene

(S)-(-)-Limonene (l-Limonene) is a Monoterpenoids,it can induce a mild bronchoconstrictive effect.

(+)-trans-Limonene oxide is an antimicrobial essential oil component that exhibits activity against Staphylococcus aureus. It can serve as a selective reagent for drug-resistant bacterial mutants without increasing the mutation frequency of Staphylococcus aureus USA300. Additionally, (+)-trans-Limonene oxide is suitable for research involving Staphylococcus aureus infections.

(S)-Limonene 3-monooxygenase (EC 1.14.13.47) is a heme-thiolate protein (P-450).

(S)-Limonene 6-monooxygenase (EC 1.14.13.48) is a heme thiolate protein (P-450).

(R)-Limonene 6-monooxygenase (EC 1.14.13.80) exhibits stereoselectivity, enabling it to selectively produce (R)-limonene.

(4S)-Limonene synthase is a recombinant enzyme from Grand Fir (Abies grandis) known as a monoterpene synthase or cyclase. It requires Mn2+ and K+ for activity, while Mg2+ as a divalent metal ion cofactor is virtually ineffective.

(R)-Limonene synthase (EC 4.2.3.20) requires divalent metal ions for catalysis, with a preference for Mn2+. This enzyme is found in plants belonging to the genera Citrus, Anethum, and Dill.

(S)-Limonene 7-monooxygenase (EC 1.14.13.49) is a heme-thiolate protein (P-450).

Limonene (Dipentene) is a monoterpene found in citrus plants such as lemon, orange, and grape, widely used in cosmetics and household products as a fragrance, with antimicrobial, antiproliferative, antioxidant, and anti-inflammatory properties.

Limonene oxide, (-)- is a bioactive chemical.

(+)-trans-Isolimonene, a natural product (monoterpene), is isolated from essential oil.

Perillyl Alcohol is a naturally occurring monoterpene related to limonene with antineoplastic activity. Perillyl alcohol (Isocarveol) inhibits farnesyl transferase and geranylgeranyl transferase, thereby preventing post-translational protein farnesylation and isoprenylation and activation of oncoproteins such as p21-ras, and arresting tumor cells in the G1 phase of the cell cycle.

α-Pinene-oxide decyclase (EC 5.5.1.10) is an isomerase that specifically functions as an intramolecular lyase. The systematic name for this enzyme is α-pinene-oxide lyase (decyclizing), and it is also known as α-pinene-oxide lyase. This enzyme plays a role in the degradation of limonene and pinene.

α-Bisabolene synthase (EC 4.2.3.38) requires a divalent cation cofactor (Mg2+) to neutralize the negative charge of the diphosphate leaving group. In vitro, α-Bisabolene synthase (EC 4.2.3.38) can use GDP as a substrate to produce (+)-(4R)-limonene.
