Direct incorporation of hydroxyproline into protein of sycamore cells incubated at growth-inhibitory levels of hydroxyproline.
Free hydroxyproline inhibits the growth of animals1' I and plants.3-7 The mechanism of this inhibition is not known. Among the theoretically possible effects of hydroxyproline are: (1) reduction of protein synthesis by lowering proline incorporation, (2) interference with proline hydroxylation, and (3) direct incorporation of hydroxyproline resulting in nonfunctional proteins. Hydroxyproline re...
متن کاملThe Structure of Cells during Tobacco Mosaic Virus Reproduction
The submicroscopic organization of mesophyll cells from tobacco leaves systemically infected with tobacco mosaic virus (TMV) is described. After fixation with glutaraldehyde and osmium tetroxide the arrangement of the TMV particles within the crystalline inclusions is well preserved. Only the ribonucleic acid-containing core of the virus particles is visible in the micrographs. Besides the hexa...
متن کاملThe effects of cytosine arabinoside upon proliferating epithelial cells.
Experiments were conducted to obtain additional insight into the response patterns of the intestinal crypts to 1-0-D-arabinofuranosylcytosine, a potent inhibitor of DNA synthesis. The results indicate that this interference with nucleic acid metabolism is not lethally toxic to the crypt epithelial cells. This formulation is based on the following observations: (a) the absence of definitive ultr...
متن کاملSensitivity of stromal elements from human bone marrow cells to cytosine arabinoside in vitro.
Cytosine arabinoside (Ara-C) is one of the most effective agents in the treatment of acute myelogenous leukemia (AML). Recently, low-dose Ara-C therapy has been the subject of topical interest in view of its differentiation-inducing effect on leukemic blast cells. Many patients, however, develop severe aplasia with low-dose Ara-C therapy [1,6,10,11]. The aim of our study was to obtain some info...
متن کاملA hydroxyproline-containing glycopeptide released from the walls of sycamore tissue-culture cells by hydrazinolysis.
Degradation of the sycamore cell wall by hydrazinolysis yielded soluble glycopeptides. The peptide portion of the predominant glycopeptide was shown to be cyclic (4-trans-hydroxy-l-prolyl)-4-trans-hydroxy- l-proline. From this structure and the composition of the major glycopeptide it was deduced that only short oligosaccharides are attached to the hydroxyprolyl residues of the wall glycoprotei...
