Concentrations of N-methyl-N′-nitro-N-nitrosoguanidine and N-methyl-N-nitroso-p-toluenesulfonamide, which temporarily inhibit the growth of Euglena gracilis Z, inhibit the synthesis of DNA, RNA, and protein. Nucleic acid synthesis (both RNA and DNA) is inhibited immediately, and protein synthesis becomes inhibited after 45–60 min.

Euglena Gracilis Z

A low molecular weight, heat-stable factor has been purified from Euglena gracilis supernatant fraction by employing gel filtration, cation and anion exchange and paper chromatography. This endogenous compound stimulates porphobilinogenase (PBG-ase) (EC 4.3.1.8) activity, an enzyme of the porphyrin biosynthetic pathway. 10-7 ᴍ folic acid and 10-4 ᴍ 6-biopterin produced a significant activation, equivalent to 2-4 units of the purified factor. Elution patterns from the columns and fluorescence and UV absorption peaks suggest that this compound is a pteridine. This conclusion is further supported by the fact that both, folic acid and 6-biopterin can replace the action of the isolated factor on PBG-ase. The mechanism of stimulation is discussed.
