Orientation of chlorophyll in vivo. Studies with magnetic field oriented chlorella

The streptomycetes have a bacterial-type cell wall and a mycelial growth habit. Although the exact taxonomic relationship to yeasts or fungi and the bacteria is unknown, a great similarity to bacteria is assumed. $\text{Streptomyces erythreus}$ CA340 (Abbott) is found to possess a multienzyme complex making fatty acids. The crude enzyme complex is stimulated by FMN; is inhibited by iodoacetamide; is excluded and partially purified (ca. 70-fold) by Sephadex G-200; is most active at pH 7.5; is most stable in 0.5 M phosphate buffer. Thus, $\text{S. erythreus}$ CA340 and possibly all streptomycetes have a major biochemical similarity to yeasts and fungi.
