Abstract

A purified sulfohydrolase having a purity level based on total amount of protein of at least about 40 wt %. Isolated nucleic acid sequence and amino acid sequences. A process for purifying at least one sulfohydrolase, including subjecting an extract from seaweed to fractionation to obtain fractions; and subjecting at least one of the fractions to phenyl sepharose chromatography to obtain sepharose fractions containing at least one sulfohydrolase. An enzymatically modified compound which has been modified by an isolated sulfohydrolase having a purity level based on total amount of protein of at least about 40 wt %. A process of enzymatically modifying a sulfated compound, including combining at least one sulfohydrolase, having a purity level based on total amount of protein of at least about 40 wt %, with a sulfated compound form a reaction mixture; and incubating the reaction mixture to remove sulfate groups from the sulfated compound to form an enzymatically modified compound. A process of enzymatically modifying a sulfated compound, including incubating a first sulfohydrolase with a sulfated compound to remove sulfate groups from the sulfated compound to form an intermediate comp…
