Microbodies inCrithidia fasciculata

Protoplasma, 1973
Electron 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.

FURTHER OBSERVATIONS ON INTRANUCLEAR MICROBODIES

British Journal of Dermatology, 1968
SUMMARY.— 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 ...

Microbodies

2013
This chapter identifies microbodies as globular-shaped organelles surrounded by a single biological membrane. It highlights three types of microbodies that are recognizable in different types of cells: peroxisomes, glyoxysomes, and glycosomes. It also describes peroxisomes as roughly spherical organelles that are widely distributed in eukaryotes and ...

Uricase: Localization in Hepatic Microbodies

Science, 1964
Microbodies of rat hepatic cells and hepatomas contain a crystalloid with the same structural characteristics as crystals of purified uricase, when viewed by electron microscopy. We conclude that crystalline uricase is located within hepatic microbodies.

Microbodies in conifer needle mesophyll

Protoplasma, 1974
Microbodies are described in the mesophyll tissue of several conifer species. Cytochemical staining ofPinus strobus andPicea mariana with 3,3′ diaminobenzidine indicated the presence of catalase in microbodies. In older tissue microbody staining was variable with peroxidative activity occurring in mesophyll cell walls and the cytoplasm.

Microbody of n-alkane-grown yeast

Archives of Microbiology, 1977
Microbodies 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.

Immobilization of yeast microbodies and the properties of immobilized microbody enzymes

European Journal of Applied Microbiology and Biotechnology, 1978
Yeast microbodies isolated from methanol-grown cells of Kloeckera sp. No. 2201 were immobilized by two types of entrapping techniques: photocrosslinking of liquid oligomers of suitable photosensitive resins and crosslinking of albumin molecules with glutaraldehyde.

Involvement of microbodies in penicillin biosynthesis

Biochimica et Biophysica Acta (BBA) - General Subjects, 1992
Penicillium 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.

Proliferation of microbodies in Saccharomyces cerevisiae

Yeast, 1987
AbstractThe 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.
