MetaCyc Reaction: 3.1.1.5

Superclasses: Reactions Classified By Conversion Type Simple Reactions Chemical Reactions
Reactions Classified By Substrate Small-Molecule Reactions

EC Number: 3.1.1.5

Enzymes and Genes:
multifunctional acyl-CoA thioesterase I and protease I and lysophospholipase L1 Inferred from experiment : tesA ( Escherichia coli K-12 substr. MG1655 )
phospholipase B : PLB3 ( Saccharomyces cerevisiae )
phospholipase B/lyso-phospholipase : PLB2 ( Saccharomyces cerevisiae )
phospholipase B/lyso-phospholipase : PLB1 ( Saccharomyces cerevisiae )
Neuropathy Target Esterase : NTE1 ( Saccharomyces cerevisiae )

Reaction Locations: periplasmic space (sensu Gram-negative Bacteria)

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.

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.
