Sulphation of a cell surface glycoprotein from Volvox carteri. Evidence for a membrane-bound sulfokinase working with PAPS.
Sulphated glycoproteins have been implicated in the control of cell growth and differentiation: fibronectins [ 1,2]; glycoproteins in developing sea urchin embryos [3]; and a surface glycoprotein from V&ox curteri [4]. This V&ox glycoprotein, of 185 000 app. M, [4] appears to be involved in the control of the differentiation of the organism during embryogenesis. Although PAPS or APS must be inv...
متن کاملPurification and partial characterization of a glycoprotein sexual inducer from Volvox carteri.
A method is described for the isolation and purification of the sexual inducer produced by male colonies of the colonial green alga Volvox carteri. The procedure yields a highly purified preparation of the inducer. The biologically active principal is demonstrated to be a glycoprotein with a molecular weight of 32,000.
متن کاملSexual Induction in Volvox Carteri
The study of the dependence of reactions on the concentration of various compounds is often of great value in determining reaction mechanisms . In chemical kinetics, it is often found that, according to van't Hoff's rule, the order of dependence of a reaction on the concentration of some compound involved in that reaction is equal to the number of molecules of the compound involved in each reac...
متن کاملA Preliminary Genetic Investigation of VOLVOX CARTERI.
A preliminary genetic analysis of a number of genetic variants of Volvox carteri f. nagariensis is presented. Techniques are outlined for mutagenesis of Volvox, isolation of mutants and routine genetic analysis. All of the mutants show simple Mendelian segregation patterns and have been tentatively placed in 14 linkage groups.
متن کاملSulphation-desulphation of a membrane component proposed to be involved in control of differentiation in Volvox carteri.
In the developing asexual embryo of Y&XX carteri the differentiation into somatic and reproductive cells is seen at the division from 32-64 cells. At this stage, 16 cells of the 32celled embryo undergo unequal cleavage, forming 16 large reproductive cells [ 1,2]. In sexual embryos developing under the influence of an inducer the differentiating cleavage is delayed in the male strain up to the f...
