Gene : OASA1 A. thaliana

DB identifier  ? AT4G14880 Secondary Identifier  ? locus:2130419
Name  ? O-acetylserine (thiol) lyase (OAS-TL) isoform A1 Brief Description  O-acetylserine (thiol) lyase (OAS-TL) isoform A1
TAIR Computational Description  O-acetylserine (thiol) lyase (OAS-TL) isoform A1;(source:Araport11)
TAIR Curator Summary  Encodes a cytosolic isoform of cytosolic O-acetylserine(thiol)lyase, a key enzyme in cysteine biosynthesis and for the fixation of inorganic sulfide. It catalyzes the formation of cysteine from O-acetylserine and inorganic sulfide. Gene expression is predominant in the root cortex and the xylem parenchyma. Gene expression is induced in leave, stems and roots by high salt and heavy metal stresses, mediated by ABA. Lines carrying semi-dominant mutations exhibit early senescence. Required for pollen tube growth and/or fertilization.
TAIR Short Description  O-acetylserine (thiol) lyase (OAS-TL) isoform A1
TAIR Aliases  ATCYS-3A, CYTACS1, OASA1, OLD3
