PTS — Pisum sativum

Summary

PsPTS (PSAT3G144240) on garden pea chromosome 3LG5 encodes a pantothenate synthetase with pantoate-beta-alanine ligase activity (EC 6.3.2.1), a homodimeric enzyme that catalyzes the ATP-dependent condensation of pantoate and beta-alanine to form pantothenate. The gene is associated with pantothenate anabolism pathways and cofactor biosynthesis, and its product localizes to the cytosol. Annotated phenotypes link PsPTS to embryo arrest at the preglobular stage, seed deformation, and embryo lethality. Related genes in other species are linked to pantothenate biosynthesis, embryo development, seed growth, germination, plant dry weight, root branching, and phosphorus uptake.
