Lactic and Α-glycerophosphate Dehydrogenases in Insects
Different tissues, especially muscles, from insects belonging to various groups were extracted and studied for their lactic dehydrogenase (LDH) and alpha-glycerophosphate dehydrogenase (GDH I) activities from the comparative point of view. In all cases assays of flight muscle extracts showed extremely low values of LDH activity whereas the GDH activities were surprisingly high. The activities i...
متن کاملThe Α-glycerophosphate Cycle in Drosophila Melanogaster
"Null" mutations previously isolated at the alphaGpdh-1 locus of Drosophila melanogaster, because of disruption of the energy-producing alpha-glycerophosphate cycle, severely restrict the flight ability and relative viability of affected individuals. Two "null" alleles, alphaGpdh-1(BO-1-4), and alphaGpdh-1(BO-1-5,) when made hemizygous with a deficiency of the alphaGpdh-1 locus, Df(2L)GdhA, wer...
متن کاملStructure and proposed mechanism of L-α-glycerophosphate oxidase from Mycoplasma pneumoniae.
UNLABELLED The formation of H2 O2 by the FAD-dependent L-α-glycerophosphate oxidase (GlpO) is important for the pathogenesis of Streptococcus pneumoniae and Mycoplasma pneumoniae. The structurally known GlpO from Streptococcus sp. (SspGlpO) is similar to the pneumococcal protein (SpGlpO) and provides a guide for drug design against that target. However, M. pneumoniae GlpO (MpGlpO), having < 20%...
متن کاملBacteriocin and hemolysin from Streptococcus faecium.
The bacteriocin and hemolysin produced by a Streptococcus faecium strain were partially separated after gel filtration on Ultrogel AcA-22. The molecular weight of bacteriocin was approximately 300,000, and that of hemolysin was 220,000. Non-bacteriocinogenic mutants retained the hemolytic activity. Production of hemolysin required glucose, whereas that of bacteriocin did not.
متن کاملStreptococcus faecium var. casselifavus, nov. var.
Streptococcus faecium var. casseliflavus is a gram-positive, spherical cell. The cells occur chiefly as pairs within chains and elongate to ogive-shaped cells during growth. Growth is good on 5% bile salts-agar and in broth at 10 C, and in broth adjusted to pH 9.6 or containing 6.5% NaCl, but many strains fail to grow at 45 C. Litmus is reduced rapidly prior to formation of an acid curd. Few st...
