enzyme that digests the sugar in juices to get rid of cloudy appearance

trypsin

serine protease that breaks down denatured proteins to remove stains

alkaline extracellular proteases

enzymes that is resistant to alkaline pH and surfactants, allowing them to act as better detergents

acid cellulases

used in biopolishing in the textile industry

pectinases

used in scouring in textile industry; removal of impurities in cotton that prevent drying

a-amylases

catalase

enzyme used in pleach removal in the textile industry

phenylketonuria

a genetic disease where phenyl ketone bodies are excreted in urine and tyrosine concentrations are low, caused by mutations of phenylalanine hydroxylase

phenylalanine hydroxylase (PAH)

the enzyme that breaks down phenylalanine to tyrosine

Treatment of phenylketonuria

diagnosis at birth, dietary control of phenylalanine, synthetic cofactor drug, enzyme substitution therapy

Sapropterin

the synthetic cofactor drug used to treat pku by increasing residual PAH activity

peglivase (palynziq)

the drug used in enzyme substitution therapy for pku which breaks phenylalanine down to cinnamic acid and ammonia
