Involvement of microbodies in penicillin biosynthesis
Biochimica et Biophysica Acta (BBA) - General Subjects, 1992Penicillium chrysogenum strains were constructed which express a mutant acyltransferase lacking the putative targeting signal for microbody proteins. The mutated enzyme was located in vacuoles and in neighbouring cytoplasm. Although acyltransferase was expressed in vivo and was active in vitro, the mutants did not produce penicillin.

FURTHER OBSERVATIONS ON INTRANUCLEAR MICROBODIES
British Journal of Dermatology, 1968SUMMARY.— The authors have observed the presence of intranuclear micro-bodies, 0·4—2·5 μ in size, containing osmiophilic particles 200 A. in size, in 1 of 2 cases of oral leukoplakia and in 1 of 7 cases of bullous erythema multiforme. The different types of intranuclear microbodies so far reported in various dermotoses are classified and their ...

Chara fragilis possesses microbodies with a remarkably large size of up to 2 µm in diameter. Many of the organelles contain huge nucleoids of amorphous material or paracrystalline inclusions. After isolation of the organelles by gradient centrifugation the specific density of the microbodies was determined to be 1.25 g cm−3.

Proliferation of microbodies in Saccharomyces cerevisiae
Yeast, 1987AbstractThe development of microbodies in the yeast Saccharomyces cerevisiae was studied in response to different conditions of growth. Various strains of S. cerevisiae were investigated, using cells from the exponential growth phase on glucose as an inocullum in all transfer experiments.

Microbody of n-alkane-grown yeast
Archives of Microbiology, 1977Microbodies appearing abundantly in n-alkane-grown cells of Candida tropicalis pK 233 were isolated by means of sucrose density gradient centrifugation. Electron microscopical observation showed that the microbodies isolated were intact. Localization of catalase and D-amino acid oxidase in the isolated microbodies was confirmed.

Microbodies inCrithidia fasciculata
Protoplasma, 1973Electron microscopy of thin sections ofCrithidia fasciculata showed cytoplasmic organelles 0.2–0.8 μm in diameter containing a finely granular matrix limited by a single membrane. Utilization of cytochemical techniques (DAB) for endogenous catalase revealed pronounced deposition of a highly electron-opaque material in these organelles.

Microbodies in experimentally altered cells. IX. The fate of microbodies.
The American journal of pathology, 1972Male rats were given 0.25% CPIB (ethyl chlorophenoxyisobutyrate) for 4 weeks at which time their liver cells showed the typical increase in number of microbodies (peroxisomes). During the first week after withdrawal of CPIB and simultaneous injection of allylisopropylacetamide (AIA), an inhibitor of catalase synthesis, the microbody matrix, in ...

The ultrastructure of hepatic microbodies of pigs was studied in liver samples fixed in phosphate-buffered 2% glutaraldehyde (pH 7.4) and postfixed in 2% osmium tetroxide. The microbodies were rounded or ovoid in shape and contained a granular matrix enclosed with a single limiting membrane. The matrix, in many of the organelles, contained an amorphous

Microbody proliferation and segregation cycle in the single-microbody alga Cyanidioschyzon merolae
Planta, 1999The proliferation cycle of the microbody was studied in the primitive red alga Cyanidioschyzon merolae, which contains one microbody per cell. Cells were synchronized with a dark/light cycle, and the morphology of the microbody and its interaction with other organelles were observed three-dimensionally by fluorescence microscopy, transmission electron ...

Developmental studies on microbodies in wheat leaves
Planta, 19751. In etiolated wheat (Triticum aestivum L.) leaves, the development of the microbody enzymes catalase, hydroxypyruvate reductase, and glycolate oxidase was specifically stimulated by short treatments of the seedlings with red light, although the increases were less than observed after treatment with continuous white light.
