Full text not available from this repository.O-acetyl-L-serine sulfhydrylase is an enzyme of assi-milatory sulfate reduction. It catalyses the formation of cysteine from O-acetyl-L-serine and sulfur reduced to the thiol level. The pathway begins with the formation of adenosine 5′-phosphosulfate (APS) from ATP and SO4 via ATP sulfurylase (E. C. 2. 7. 7. 4). In C4 plants ATP sulfurylase is predominantly localized in the bundle sheath cells (1, 2), while O-acetyl-L-serine sulfhydrylase was detected in meso-phyll protoplasts and bundle sheath strands (2). We have shown that various forms of O-acetyl-L-serine sulfhydrylase exist in spinach (3) and Phaseolus vulgaris (4). These findings taken together prompted us to examine, whether different forms of the enzyme occured in mesophyll cells and bundle sheath cells of the C4 plant Zea mays. For comparison, we included wheat (Triticum aestivum), a C3 grass.
