They bind with the protein molecule (apoenzyme) to form the active enzyme
(holoenzyme).
serve as coenzyme
Vit. B1, B2, B6 –
These are inorganic ions that bind to enzymes and increase their activity. Ex: fructose 2,6-biphosphate which activates phosphofructokinase 1
ACTIVATORS
Employed as digestants
Pepsin, Pancreatin, Papain
Facilitates the diffusion of injected fluids
Hyaluronidase
Dissolve clotted blood & purulent accumulations
Streptokinase & Streptodornase
Used in fermentation & cheese industries
Zymase & Rennin
Inactivates the various penicillins
Penicillinase
THE AMYLOLYTIC ENZYMES OF CHO
❖ Diastase & amylase
❖ Malt diastase.
❖ Invertase or sucrase
❖ Maltase
❖ Zymase
❖ Emulsin
❖ Myrosin
salivary diastase, found in digestive tract of animals.
Ptyalin
pancreatic diastase, found in digestive tract of animals (they are sometimes called “animal diastase”.
Amylopsin
formed during the germination of barley grains and converts starch into maltose.
MALT DIASTASE
is found in yeast & in the intestinal juices. It brings about the hydrolysis of sucrose into glucose & fructose.
INVERTASE OR SUCRASE
also found in yeast & the intestinal juices, which causes the conversion of maltose into glucose.
MALTASE
a fermenting enzyme causing the conversion of monosaccharides into alcohol & CO2.
ZYMASE
an enzyme found in almonds. It causes the hydrolysis of β-glycosides, amygdalin into glucose, benzaldehyde, & hydrogen cyanide.
EMULSIN
found in white & black mustard, it hydrolyzes sinalbin, sinigrin and other glycosides
MYROSIN
II. THE ESTERASES
❖ Lipase
❖ Pectase
❖ Steapsin
❖ Urease
a lipolytic enzyme found in both animal & vegetable kingdom. Found in the pancreatic juice of animals & in oily seeds. It causes the hydrolysis of fats into glycerin & fatty acids.
LIPASE
splits pectin into pectic acid & methyl alcohol
PECT
