The alteration by an organism of the levels of indole acetic acid in the host organism. The host is defined as the larger of the organisms involved in a symbiotic interaction.

The process by which a symbiont acquires iron from its host, either from heme or other iron containing molecules such as transferrin and lactoferrin. Begins with either the secretion of symbiont gene products that bind iron- or heme-containing molecules (siderophores and hemophores) from the symbiont cell into the host, or by expression of receptors that bind iron- or heme-containing molecules on the symbiont cell surface. Ends when the iron-containing compound is transported into the symbiont cell.

The process that begins with the production and formation of structures and molecules in an organism that are required for the acquisition and utilization of nutrients from its host organism, and the ends with the acquirement of the nutrients. The host is defined as the larger of the organisms involved in a symbiotic interaction.

A biological process represents a specific objective that the organism is genetically programmed to achieve. Biological processes are often described by their outcome or ending state, e.g., the biological process of cell division results in the creation of two daughter cells (a divided cell) from a single parent cell. A biological process is accomplished by a particular set of molecular functions carried out by specific gene products (or macromolecular complexes), often in a highly regulated manner and in a particular temporal sequence.

A type of ovulation cycle, which occurs in most mammalian therian females, where the endometrium is resorbed if pregnancy does not occur.

A lysosome-related organelle contained within the intestinal cells of the nematode C. elegans. Gut granules are acidified, birefringent, autofluorescent, and contain the vacuolar H+-ATPase. They also serve as sites of cellular zinc storage.

A vesicle found in the cytoplasm of a cell.

The membrane of a gut granule, a lysosome-related organelle contained within the intestinal cells of the nematode C. elegans.

A membrane that is one of the two lipid bilayers of an organelle envelope or the outermost membrane of single membrane bound organelle.

The lipid bilayer surrounding a cytoplasmic vesicle.

The lumen of a gut granule, a lysosome-related organelle contained within the intestinal cells of the nematode C. elegans.

An organelle lumen that is part of an intracellular organelle.

The internal volume enclosed by the membranes of a particular organelle; includes the volume enclosed by a single organelle membrane, e.g. endoplasmic reticulum lumen, or the volume enclosed by the innermost of the two lipid bilayers of an organelle envelope, e.g. nuclear lumen.

The chemical reactions and pathways involving the nonmetallic element sulfur or compounds that contain sulfur, such as the amino acids methionine and cysteine or the tripeptide glutathione.

The chemical reactions and pathways involving glycosaminoglycans, any of a group of polysaccharides that contain amino sugars.

The chemical reactions and pathways involving aminoglycans, any polymer containing amino groups that consists of more than about 10 monosaccharide residues joined to each other by glycosidic linkages.

The chemical reactions and pathways involving chondroitin sulfate, any member of a group of 10-60 kDa glycosaminoglycans, widely distributed in cartilage and other mammalian connective tissues, the repeat units of which consist of beta-(1,4)-linked D-glucuronyl beta-(1,3)-N-acetyl-D-galactosamine sulfate. They usually occur linked to a protein to form proteoglycans. Two subgroups exist, one in which the sulfate is on the 4-position (chondroitin sulfate A) and the second in which it is in the 6-position (chondroitin sulfate C). They often are polydisperse and often differ in the degree of sulfation from tissue to tissue. The chains of repeating disaccharide are covalently linked to the side chains of serine residues in the polypeptide backbone of a protein by a glycosidic attachment through the trisaccharide unit galactosyl-galactosyl-xylosyl. Chondroitin sulfate B is more usually known as dermatan sulfate.

The chemical reactions and pathways involving dermatan sulfate, any of a group of glycosaminoglycans with repeats consisting of beta-(1,4)-linked L-iduronyl-beta-(1,3)-N-acetyl-D-galactosamine 4-sulfate units. They are important components of ground substance or intercellular cement of skin and some connective tissues.

The chemical reactions and pathways resulting in the formation of chondroitin sulfate, any member of a group of 10-60 kDa glycosaminoglycans, widely distributed in cartilage and other mammalian connective tissues, the repeat units of which consist of beta-(1,4)-linked D-glucuronyl beta-(1,3)-N-acetyl-D-galactosamine sulfate.

The chemical reactions and pathways resulting in the breakdown of chondroitin sulfate, any member of a group of 10-60 kDa glycosaminoglycans, widely distributed in cartilage and other mammalian connective tissues, the repeat units of which consist of beta-(1,4)-linked D-glucuronyl beta-(1,3)-N-acetyl-D-galactosamine sulfate.
