Arylsulfatase (EC 3.1.6.1, sulfatase, nitrocatechol sulfatase, phenolsulfatase, phenylsulfatase, p-nitrophenyl sulfatase, arylsulfohydrolase, 4-methylumbelliferyl sulfatase, estrogen sulfatase) is a type of sulfatase enzyme with systematic name aryl-sulfate sulfohydrolase. This enzyme catalyses the following chemical reaction
: 	an aryl sulfate + HO  a phenol + sulfate
It catalyses an analogous reaction for sulfonated hexoses. Types include:
*Arylsulfatase A (also known as "cerebroside-sulfatase")
*Arylsulfatase B (also known as "N-acetylgalactosamine-4-sulfatase")
*Steroid sulfatase (formerly known as "arylsulfatase C")
*ARSC2
*ARSD
*ARSF
*ARSG
*ARSH
*ARSI
*ARSJ
*ARSK
*ARSL (formerly known as "arylsulfatase E", "ARSE")
