2.A.53.1.6
The sulfate transporter, Sultr1.2 with C-terminal STAS domain that is required both for activity and biogenesis/stability (Shibagaki and Grossman, 2006). It physically interacts with 0-acetylserine (thiol)lyase (cysteine synthetase) via its STAS domain. This interaction stimulates the activity of 0-acetylserine (thiol)lyase while inhibiting the SULTR1;2 transport activity. SULTR1.1 (TC# 2.A.53.1.7) interacts with 0-acetylserine (thiol)lyase but this interaction does not stimulate its activity (Shibagaki and Grossman, 2010).
