Promiscuous Arylsulfatase Activity in Chlamydomonas reinhardtii

Sulfate is an essential macroelement for all living organisms. However, sulfate can be limited in agricultural settings. Microorganisms change their gene expression to acclimate deficient conditions. Green microalga Chlamydomonas reinhardtii expresses and secretes extracellular arylsulfatase (ARS) under Our results show that C. ARS hydrolyze both monoester (5-bromo-4-chloro-3 indolyl sulfate; X-SO42-) phosphate phosphate; X-PO43-) providing evidence enzyme has promiscuous activity. found soil fresh water habitats nature. This activity beneficial making bioavailable uptake by organisms plant roots.
