SPS-2 was highly activated by Glc-6-P and phate-2-glucosyltransferase, EC 2.4.1.14) show that the showed low sensitivity to Pi. In vitro alkaline phosphatase protein is differently localized in photosynthetic and etio- treatment suggested that SPS-1 could be regulated as leaf lated leaves. Very little is known about SPS regulation in SPS in darkness and that SPS-2 is present in a dephosphoheterotrophic tissues; therefore, we studied the biochemical rylated state or is not regulated by protein phosphorylation. properties of the enzyme from etiolated seedlings and em- The relative MM value (116 kDa) estimated for both SPS bryo.
