Bifunctional 3'-phosphoadenosine 5'-phosphosulfate synthases 1 and 2 (PAPSS1,2) (Venkatachalam et al. 1998, Xu et al. 2000) are involved in phosphorylating adenylylselenate (APSe) into 3'-phosphoadenylyl selenate (PAPSe) via its APS kinase domain. This reaction is inferred from the event in Penicillium chrysogenum involving APS kinase (Kaps) (Yu et al. 1989).
