Disease relevance of pys

Cloning and expression in Escherichia coli of the gene coding for phytoene synthase from the cyanobacterium Synechocystis sp. PCC6803 [1].

High impact information on pys

The sequences of the genes encoding the yeast isopentenyl diphosphate isomerase (ipi) and the Synechocystis beta-carotene hydroxylase (crtR) and the linked Synechocystis genes coding for phytoene desaturase and phytoene synthase (crtP and crtB, respectively) were introduced into Synechocystis, replacing the psbAII coding sequence [2].
The gene coding for the carotenoid biosynthesis enzyme phytoene synthase (pys) has been cloned from the unicellular cyanobacterium Synechocystis sp. PCC6803 [1].
Analysis of the sequence of the Synechocystis pys protein deduced from the gene sequence shows that it is highly homologous to the tomato and Synechococcus phytoene synthases and shows conserved domains with other bacterial phytoene synthase enzymes [1].
