In enzymology, a long-chain-fatty-acid—[acyl-carrier-protein] ligase (EC 6.2.1.20) is an enzyme that catalyzes the chemical reaction
- ATP + an acid + [acyl-carrier-protein] AMP + diphosphate + acyl-[acyl-carrier-protein]
The 3 substrates of this enzyme are ATP, acid, and acyl-carrier-protein, whereas its 3 products are AMP, diphosphate, and [[acyl-[acyl-carrier-protein]]].
This enzyme belongs to the family of ligases, specifically those forming carbon-sulfur bonds as acid-thiol ligases. The systematic name of this enzyme class is long-chain-fatty-acid:[acyl-carrier-protein] ligase (AMP-forming). Other names in common use include acyl-[acyl-carrier-protein] synthetase, acyl-[acyl carrier protein] synthetase, acyl-ACP synthetase, acyl-[acyl-carrier-protein]synthetase, stearoyl-ACP synthetase, and acyl-acyl carrier protein synthetase. This enzyme participates in fatty acid metabolism.

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.
