LITERATURE
additional information
-
isoforms OAS-TL A and B are the most abundant isoforms in all tissues analyzed. The major isoforms present in cytosol, plastids and mitochondria show significant modifications into up to seven subspecies. Specific isoforms are found to be differentially modified in the leaves, roots, stem and cell culture. Sulfur deficiency does not alter modification of enzyme proteins purified from cell culture that shows the highest complexity of modifications. However, the pattern of enzyme modification is found to be stable within an analyzed tissue
