|Arabidopsis thaliana col :||phospholipase A1
phospholipase A1 : AtLCAT3
acylhydrolase : DSEL
The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the direction in which it was curated.
Most BioCyc compounds have been protonated to a reference pH value of 7.3, and some reactions have been computationally balanced for hydrogen by adding free protons. Please see the PGDB Concepts Guide for more information.
Mass balance status: Balanced.
Enzyme Commission Primary Name: phospholipase A1
Standard Gibbs Free Energy (ΔrG'° in kcal/mol): -13.03833 [Latendresse13]
Enzyme Commission Summary:
This enzyme has a much broader specificity than EC 184.108.40.206 phospholipase A2. Requires Ca2+.
