In enzymology, a vitexin 2"-O-rhamnoside 7-O-methyltransferase (EC 2.1.1.153) is an enzyme that catalyzes the chemical reaction
- S-adenosyl-L-methionine + vitexin 2"-O-beta-L-rhamnoside S-adenosyl-L-homocysteine + 7-O-methylvitexin 2"-O-beta-L-rhamnoside
Thus, the two substrates of this enzyme are S-adenosyl methionine and vitexin 2"-O-beta-L-rhamnoside, whereas its two products are S-adenosylhomocysteine and 7-O-methylvitexin 2"-O-beta-L-rhamnoside.
This enzyme belongs to the family of transferases, specifically those transferring one-carbon group methyltransferases. The systematic name of this enzyme class is S-adenosyl-L-methionine:vitexin-2"-O-beta-L-rhamnoside 7-O-methyltransferase.

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
