Biochemistry Enzyme Types

Oxiodoreductase

Transfer of electrons or H atoms

Subtype of Oxiodoreductase #1: Oxidase

Oxidizes without transfer of H atoms

Subtype of Oxiodoreductase #2: Dehydrogenase

Removal of H atoms = Oxidation

Subtype of Oxiodoreductase #3: Kinase

Transfer of phophoryl groups

Hydrolase

Breaks bond to produce water as a byproduct

Subtype of hydrolase #1: Phosphatase

Removes phosphate group by hydrolysis

Phosphorylase

Catalyzes breaking of bonds using inorganic phosphate

Lyase

Cleavage of carbon bonds by elimiation, leaving double bonds or addition of groups to double bonds

Subtype of Lyase #1: Synthase

Two groups joined WITHOUT NTP energy

Subtype of Lyase #2: Hydratase

Adds water

Subtype of Lyase #3: Decarboxylase

Does decarbocylation

Isomerase

Transfer of groups or double bonds within the molecule

Subtype of Isomerase #1: Mutase

Moves functional groups within a molecule

Ligase/Synthetase (subtrate level phosphorylation)

Two groups joined WITH NTP energy

Translocase

Transport of molecules or ions across membranes

Enolase (Specialized to Reaction 9)

Dehydrates (removes water) from 2-phospoglycerate to form the unstable enol of phosphoenolpyruvate

Aldolase

Cleaves fructose 1,6 - biphosphate along the C3-C4 bond to make glyceraldehyde 3-phosphate (start counting from the aldehyde carbon 4, 5, 6 of OG but carbon bonded to phosphate now carbon 1) and dehydroxyacetone phosphate (start counting from the carbon bonded to phosphate group 1, 2, 3 of OG)

Fumrase

Hydratase that adds water across double bond to make it single bond Reaction 7 of Krebs Cycle
