Microbodies are novel pharmacophoric entities which are derived from naturally occurring cystine-knot microproteins. They provide extremely stable scaffolds that can be engineered to high-affinity binding proteins. A peptide-grafting approach yielded specific ligands for human thrombopoietin receptor (TPO-R).

The ultrastructure and cytochemistry of microbodies inPorphyridium
Protoplasma, 1974This work establishes the presence of a microbody-like organelle in a unicellular red alga,Porphyridium purpureum (Bory) Drew et Ross. There are several of these per cell. They are spherical or slightly ovoid in shape and 0.2–0.4 microns in diameter.

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 ...

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.

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.

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 ...

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.

The ultrastructure and cytochemistry of microbodies in dinoflagellates
Planta, 1973Microbodies, similar in morphology to those of higher plants and animals, have been observed in thirteen genera of dinoflagellates. As in other unicellular algae, they did not show any staining after incubation in DAB/H2O2 medium although the mitochondrial cristae and chloroplast lamellae did give a positive reaction.

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.
