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.

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 ...

Microbodies of the alga Chara

Physiologia Plantarum, 2003
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, 1973
Microbodies, 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.

Visualization of microbodies in Chlamydomonas reinhardtii

Journal of Plant Research, 2011
In Chlorophycean algal cells, these organelles are generally called microbodies because they lack the enzymes found in the peroxisomes of higher plants. Microbodies in some algae contain fewer enzymes than the peroxisomes of higher plants, and some unicellular green algae in Chlorophyceae such as Chlamydomonas reinhardtii do not possess catalase, an ...

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.

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.

Developmental studies on microbodies in wheat leaves

Planta, 1975
1. 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.

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.
