Publikováno v: Journal of Bacteriology. 180:4416-4425

Cyclic di-GMP (c-di-GMP) acts as a reversible and highly specific positive effector of cellulose (1,4-β-d-glucan) synthase in the cellulose-producing bacterium Acetobacter xylinum (34, 35; for a review, see reference 36). This unique nucleotide stim

Glycosylated Triterpenoid Saponin: a Specific Inhibitor of Diguanylate Cyclase from Acetobacter xylinum. Biological Activity and Distribution

Autor: Moshe Benziman, Patricia Ohana, Gail Volman, Deborah P. Delmer

Publikováno v: Plant and Cell Physiology. 39:153-159

In a recent paper (Ohana et al. 1998), we described the purification and structural characterization of a novel glycosidic triterpenoid saponin (GTS), a specific inhibitor of diguanylate cyclase (dgc), the key regulatory enzyme of the cellulose synth

Genetic data indicate that proteins containing the GGDEF domain possess diguanylate cyclase activity

Autor: Dorit Amikam, Raphael Mayer, Nora Ausmees, Martin Lindberg, Haim Weinhouse, Moshe Benziman, Gail Volman

Publikováno v: FEMS microbiology letters. 204(1)

A conserved domain, called GGDEF (referring to a conserved central sequence pattern), is detected in many procaryotic proteins, often in various combinations with putative sensory-regulatory components. Most sequenced bacterial genomes contain severa

Phosphodiesterase A1, a regulator of cellulose synthesis in Acetobacter xylinum, is a heme-based sensor

Autor: Raphael Mayer, Haim Weinhouse, Gail Volman, Alan L. Chang, Dorit Amikam, Moshe Benziman, Marie Alda Gilles-Gonzalez, Jason R. Tuckerman, Gonzalo Gonzalez

Publikováno v: Biochemistry. 40(12)

The phosphodiesterase A1 protein of Acetobacter xylinum, AxPDEA1, is a key regulator of bacterial cellulose synthesis. This phosphodiesterase linearizes cyclic bis(3'--5')diguanylic acid, an allosteric activator of the bacterial cellulose synthase, t

c-di-GMP-binding protein, a new factor regulating cellulose synthesis in Acetobacter xylinum

Autor: Dorit Amikam, Yehudit Shilo, Patricia Ohana, Haim Weinhouse, Moshe Benziman, Gail Volman, Shai Sapir

Publikováno v: FEBS letters. 416(2)

A protein which specifically binds cyclic diguanylic acid (c-di-GMP), the reversible allosteric activator of the membrane-bound cellulose synthase system of Acetobacter xylinum, has been identified in membrane preparations of this organism. c-di-GMP

Publikováno v: Plant physiology. 98(2)

In a recent paper (P Ohana, DP Delmer, JC Steffens, DE Matthews, R Mayer, M Benziman [1991] J Biol Chem 266: 13472-13475), we described the purification and structural characterization of beta-furfuryl-beta-glucoside (FG), an endogenous activator of

Polypeptide composition of bacterial cyclic diguanylic acid-dependent cellulose synthase and the occurrence of immunologically crossreacting proteins in higher plants

Autor: Peter Ross, Hing C. Wong, Moshe Benziman, Dorit Amikam, Haim Weinhouse, Raphael Mayer, Gail Volman, Roger D. Calhoon, Ann W. Emerick, Patricia Ohana

Publikováno v: Proceedings of the National Academy of Sciences of the United States of America. 88(12)

To comprehend the catalytic and regulatory mechanism of the cyclic diguanylic acid (c-di-GMP)-dependent cellulose synthase of Acetobacter xylinum and its relatedness to similar enzymes in other organisms, the structure of this enzyme was analyzed at
