TV-Acetyl neuraminic acid aldolase [from Clostridium perfringens, TV-acetyIneuraminic acid pyruvate lyase] [9027-60-5] 32,000 [EC 4.1.3.3]. Purified by extraction with H2O,... [Pg.507]

Samples of DNA isolated from different tissues of the same species have the same proportions of heterocyclic bases, but samples from different species often have greatly different proportions of bases. Human DNA, for example, contains about 30% each of adenine and thymine and about 20% each of guanine and cytosine. The bacterium Clostridium perfringens, however, contains about 37% each of adenine and thymine and only 13% each of guanine and cytosine. Note that in both examples the bases occur in pairs. Adenine and thymine are present in equal amounts, as are cytosine and guanine. Why ... [Pg.1103]

Commercial A -acetylneuraminic acid aldolase from Clostridium perfringens (NeuAcA EC 4.1.3.3) catalyzes the addition of pyruvate to A-acetyl-D-mannosamine. A number of sialic acid related carbohydrates are obtained with the natural substrate22"24 or via replacement by aldose derivatives containing modifications at positions C-2, -4, or -6 (Table 4)22,23,25 26. Generally, a high level of asymmetric induction is retained, with the exception of D-arabinose (epimeric at C-3) where stereorandom product formation occurs 25 2t The unfavorable equilibrium constant requires that the reaction must be driven forward by using an excess of one of the components in order to achieve satisfactory conversion (preferably 7-10 equivalents of pyruvate, for economic reasons). [Pg.591]

Another subfamily of ADP-iibosylating toxins modifies G-actin (at Argl77), thereby inhibiting actin polymerization. Members of this family are, for example, C. botulinum C2 toxin and Clostridium perfringens iota toxin. These toxins are binary in structure. They consist of an enzyme component and a separate binding component, which is structurally related to the binding component of anthrax toxin [3]. [Pg.246]

Lecithinase is produced by Clostridium perfringens. This is a calcium-dependent lecithinase whose activity depends on the ability to split lecithin. Since lecithin is present in the membrane of many different kinds of cells, damage can occur throughout the body. Lecithinase causes the hydrolysis of erythrocytes and the necrosis of other tissue cells. [Pg.282]

All earlier studies [155-158] reported the complexation of berberine with calf thymus DNA and suggested by a mechanism of intercalation. Maiti and coworkers [159-162] demonstrated first the base- and sequence-specificity of berberine from studies with several naturally occurring DNAs (Clostridium perfringenes, cholera bacteriophage 02, calf thymus, Escherichia coli, Micrococcus lysodeikticus) and synthetic DNAs ((poly(dG-dC) poly(dG-dC), poly(dG)-poly(dC), poly(dA-dT) poly(dA-dT), poly(dA)-poly(dT)) using various physicochemical techniques. Several aspects of the interaction were reported ... [Pg.178]

Another important necrotizing skin and soft tissue infection is clostridial myonecrosis (gas gangrene). Clostridial myonecrosis can develop spontaneously but most often occurs after trauma. Clostridium perfringens is the most common causative pathogen. [Pg.1081]
