Cytokinins induce two specific morphological alterations in mosses: (i) the differentiation of a tipgrowing cell into a three-faced apical cell (the so-called bud), and (ii) the division of chloroplasts. In a developmental mutant of the moss Physcomitrella patens (Hedw.) B.S.G. (mutant PC22) impeded in both cellular differentiation (bud production) and(More)
Two proteins from crayfish (Orconectes limosus) retinae bind Ca(2+)-dependently to phospholipid membranes and crossreact with an antibody against calelectrin (annexin IV). These proteins (p48 and p40) are prominent substrates for the protein carboxyl methyl transferase (PCMT) which we propose to be an intracellular protein crosslinking enzyme. Methylation(More)
The monoclonal antibody LA7 was raised against the species-specific Borrelia burgdorferi lipoprotein P22 (= IPLA7), which induces antibody formation in patients with Lyme arthritis. It is composed of 194 amino acids with a calculated molecular mass of 21.8 kDa. Its gene on the linear chromosome is 582 nucleotides in length. The aim of this study was to(More)
The enzymatic transfer of methyl groups mediated by protein methylase II onto proteins of the electroplaque tissue of Torpedo marmorata is described. The protein methylase II resides to the extent of 80% in the cytosol and 20% in the acetylcholine receptor-rich membrane. The kinetics of the methyl-group transfer are characteristically different in the(More)
Protein methylase II (protein O-methyltransferase, EC 2.1.1.24) was found in Dictyostelium discoideum amoebae, Astacus leptodactylus axonal, Locusta migratoroides neuronal, Torpedo marmorata electroplaque and Bos bovis stratial tissue and compared in both the soluble and particulate fractions. The intrinsic decay data of the methyl groups transferred onto(More)
