Two isoforms o f glutam ine synthetase, G S | a n d G S 2, have been separated from Chlamy­ domonas reinhardii cells grown auto trophically w ith nitrate. T he in tracellu lar level o f G S 2 was higher than that o f G S , . In cells under darkness, the G S, peak increased m arkedly, w hereas that o f GS2 became negligible.
