Plastocyanin microheterogeneity in Scenedesmus acutus MT8.
Two total plastocyanin (PC) fractions - loosely bound (lPC) and strongly bound (sPC) were extracted (84% and 16%, respectively) from the homogenate of Scenedesmus acutus MT8. Two-fold isolation-purification procedure including DE-52 chromatography separated IPC into a smaller oxidized [IPC (II)] and a larger reduced [IPC(I)] fractions, in contrast to sPC, where sPC(ll) greatly dominated over sP...
متن کاملPuriication and some properties of Scenedesmus ferredoxin.
A simple procedure for purification of ferredoxin from a green alga, Scenedesmus, is described. Crystalline ferredoxin had an absorption spectrum with maxima at 276, 330, 421, and 464 rnp and with minima at 255, 293, 390, and 445 rnp. The ratios of the optical densities at 421 and 330 rnp to that at 276 rnp were 0.651 and 0.883, respectively. The substance was shown to be pure by disc electroph...
متن کاملThe Non-essentiality of Boron for Scenedesmus.
It is generally assumed in plant nutrition that an essential element is essential for all plants, though the amounts required may be appreciably different. Thus, the need for boron is shown within 3 to 4 days by the necrosis of sunflower, tomato, or tobacco tissue, but requires at least 3 weeks in soybeans. The suggestion (3) that boron was required for differentiation rather than cell division...
متن کاملThe amino acid sequence of Scenedesmus ferredoxin.
The complete amino acid sequence of ferredoxin isolated from a green alga, Scenedesmus species, was determined by analyses of tryptic and chymotryptic digests, and cyanogen bromide cleavage of the S-carboxymethylcysteinylferredoxin. The total number of amino acid residues is 96, one less than for the higher plant ferredoxins. It is the first chloroplasttype ferredoxin found lacking in tryptopha...
متن کاملTransfer ribonucleic acid from Scenedesmus obliquus D3.
Scenedesmus obliquus is a green alga whose cells have a well-defined nucleus, and contain a chloroplast. Even when grown in the dark these cells retain their chloroplast. Because of the toughness of the cell wall, extraction of tRNA requires either vigorous homogenization of the cells before phenol extraction or prolonged phenol extraction at 60°C. Determination of the amount of tRNA and its pu...
