Journal articles and databases are two major modes of communication in the biological sciences, and thus integrating these critical resources is of urgent importance to increase the pace of discovery. Projects focused on bridging the gap between journals and databases have been on the rise over the last five years and have resulted in the development of(More)
The effects of gangliosides on phosphorylation were studied in rat brain membrane. Gangliosides stimulated phosphorylation only in the presence of Ca2+ with major phosphoproteins of 45,000, 50,000, 60,000, and 80,000 daltons and high-molecular-weight species. In addition, gangliosides inhibited the phosphorylation of three proteins with molecular weights of(More)
The nucleotide sequence of a spinach chloroplast proline tRNA (sp. chl. tRNApro) has been determined. This tRNA shows more overall homology to phage T4 proline tRNA (61% homology) than to eukaryotic proline tRNAs (53% homology) or mitochondrial proline tRNAs (36-49% homology). Sp. chl. tRNApro, like all other chloroplast tRNAs sequenced, contains a(More)
The effects of folic acid on synaptic transmission in the hippocampal slice have been studied. Application of folic acid (0.1-1 mM) increased the size of population spikes recorded extracellularly in the CAl pyramidal cell layer and caused the appearance of multiple population spikes. Intracellular recording revealed that folic acid had no consistent effect(More)
The nucleotide sequence of a spinach chloroplast valine tRNA (sp. chl. tRNA Val) has been determined. This tRNA shows essentially equal homology to prokaryotic valine tRNAs (58-65% homology) and to the mitochondrial valine tRNAs of lower eukaryotes (yeast and N. crassa, 61-62% homology). Sp. chl. tRNA Val shows distinctly lower homology to mouse(More)
