'The recruitment of FtsZ to the septum and its subsequent interaction with other cell division proteins in a spatially and temporally controlled manner are the keys to bacterial cell division. In the present study, we have tested the hypothesis that FtsZ and FtsW of Mycobacterium tuberculosis could be binding partners. ... More
Tight Binding Inhibition of Protein Phosphatase-1 by Phosphatidic Acid. SPECIFICITY OF INHIBITION BY THE PHOSPHOLIPID.
Authors: Jones Jeffrey A; Hannun Yusuf A;
Journal:J Biol Chem
PubMed ID:11856740
'Phosphatidic acid (PA) has been identified as a bioactive lipid second messenger, yet despite extensive investigation, no cellular target has emerged as a mediator of its described biological effects. In this study, we identify the gamma isoform of the human protein phosphatase-1 catalytic subunit (PP1cgamma) as a high affinity in ... More
Biochemical properties of the PsbS subunit of photosystem II either purified from chloroplast or recombinant.
'The biochemical properties of PsbS protein, a nuclear-encoded Photosystem II subunit involved in the high energy quenching of chlorophyll fluorescence, have been studied using preparations purified from chloroplasts or obtained by overexpression in bacteria. Despite the homology with chlorophyll a/b/xanthophyll-binding proteins of the Lhc family, native PsbS protein does not ... More
Genetic and biochemical properties of streptococcal NAD-glycohydrolase inhibitor.
Authors:Kimoto H, Fujii Y, Hirano S, Yokota Y, Taketo A,
Journal:J Biol Chem
PubMed ID:16380378
'The gene encoding streptolysin O (slo), a cytolysin of hemolytic streptococci, is transcribed polycistronically from the promoter of the preceding NAD-glycohydrolase (NADase) gene (nga). Between nga and slo, a putative open reading frame (orf1) is located whose function has been totally unknown. Present investigation demonstrated that the orf1 encodes a ... More
Assimilation of nicotinamide mononucleotide requires periplasmic AphA phosphatase in Salmonella enterica.
Authors:Grose JH, Bergthorsson U, Xu Y, Sterneckert J, Khodaverdian B, Roth JR,
Journal:J Bacteriol
PubMed ID:15968063
'Salmonella enterica can obtain pyridine from exogenous nicotinamide mononucleotide (NMN) by three routes. In route 1, nicotinamide is removed from NMN in the periplasm and enters the cell as the free base. In route 2, described here, phosphate is removed from NMN in the periplasm by acid phosphatase (AphA), and ... More
