Demethylspheroidene O-methyltransferase (EC 2.1.1.210, 1-hydroxycarotenoid O-methylase, 1-hydroxycarotenoid methylase, 1-HO-carotenoid methylase, CrtF) is an enzyme with systematic name S-adenosyl-L-methionine:demethylspheroidene O-methyltransferase. [1] [2] [3] This enzyme catalyses the following chemical reaction

S-adenosyl-L-methionine + demethylspheroidene S-adenosyl-L-homocysteine + spheroidene

In Rhodopseudomonas capsulata and Rubrivivax gelatinosus the enzyme is involved in biosynthesis of spheroidene.

DNA adenine methylase, (Dam methylase) (also site-specific DNA-methyltransferase (adenine-specific), EC 2.1.1.72, modification methylase, restriction-modification system) is an enzyme that adds a methyl group to the adenine of the sequence 5'-GATC-3' in newly synthesized DNA. Immediately after DNA synthesis, the daughter strand remains unmethylated for a short time. It is an orphan methyltransferase that is not part of a restriction-modification system and regulates gene expression. This enzyme catalyses the following chemical reaction
