OsVTC1-1 RNAi Mutant with Reduction of Ascorbic Acid Synthesis Alters Cell Wall Sugar Composition and Cell Wall-Associated Proteins

Amino acid composition of certain bacterial cell-wall proteins.

Analyses were made to determine the amino acid composition of the cell-wall proteins of Salmonella pullorum, S. senftenberg 775W, S. derby, and Escherichia coli. These proteins consist of the usual 18 amino acids found in most proteins with diaminopimelic acid in addition. Quantitative determination of these amino acids showed that their amounts were similar.

Cell wall composition of lactic acid bacteria.

After the discovery of methods for the isolation of bacterial cell walls (l), it was established that walls of gram-positive organisms contain relatively few amino acids. The most frequently occurring and abundant of these are alanine, glutamic acid, aspartic acid, lysine, and diaminopimelic acid. Walls of grampositive organisms also contain large amounts of sugars and amino sugars and are rela...

1-aminoethylphosphonic acid, an inhibitor of bacterial cell wall synthesis.

Sir: There are numerous steps in bacterial cell wall synthesisll) but the compounds inhibiting this synthesis are limited. To this group of compounds, i. e. penicillins2), cephalosporins2), ristocetin6), vancomycin7), bacillin1^ moenomycin5), prasinomycin9), cycloserine10), O-carbamyl-D-serine10), glycine8), and damino acids3) can be added 1-aminoethylphosphonic acid (AEPA). When titrated again...

Cell wall proteins from sugar beet cells in suspension culture.

Several proteins were extracted from the purified cell walls of suspension-cultured sugar beet cells with 0.5% EDTA (pH 6.8) after prior extraction of the walls with 0.5% deoxycholate and then with 2 molar NaCl. Two abundant proteins (P-I and P-II protein) were separately purified to homogeneity by procedures that included fractionation with ammonium sulfate, column chromatography on DEAE-cellu...
