    The Arabidopsis thaliana HAL3 gene product encodes for an FMN-binding protein (AtHal3) that is related to plant growth and salt and osmotic tolerance. AtHal3 shows sequence homology to ScHal3, a regulatory subunit of the Saccharomyces cerevisae serine/threonine phosphatase PPz1. It has been proposed that AtHal3 and ScHal3 have similar roles in cellular physiology, as Arabidopsis transgenic plants that overexpress AtHal3 and yeast cells that overexpress ScHal3 display similar phenotypes of improved salt tolerance. The enzymatic activity of AtHal3 has not been investigated. However, the AtHal3 sequence is homologous to that of EpiD, a flavoprotein from Staphylococcus epidermidis that recognizes a peptidic substrate and subsequently catalyzes the alpha, beta-dehydrogenation of its C-terminal cysteine residue.
