Enzyme activities of cell homogenates and chloroplasts from Chlamydomonas reinhardtii wild-type and sta8 strains

Enzymes	Wild Type		sta8
	Homogenate	Chloroplasts	Homogenate	Chloroplasts
UGPase	609 ± 36	116 ± 15	567 ± 38	126 ± 14
Phosphoenolpyruvate carboxylase	12 ± 0.7	2.2 ± 0.3	10 ± 1	1.6 ± 0.2
NADP GAP DH	138 ± 6	184 ± 11	120 ± 6	159 ± 4
Isoamylase	9.4 ± 0.3	10.2 ± 0.8	2.6 ± 0.1	3.7 ± 0.1

Activities are expressed in micromoles per milligram of chlorophyll per hour and are the average of three separate measures.
