A linear polysaccharide of beta-1->4 linked units of ACETYLGLUCOSAMINE. It is the second most abundant biopolymer on earth, found especially in INSECTS and FUNGI. When deacetylated it is called CHITOSAN.

An enzyme that converts UDP glucosamine into chitin and UDP. EC 2.4.1.16.

Chitinase is an enzyme that catalyzes the hydrolysis of chitin, a polysaccharide that makes up the exoskeleton of insects and the cell walls of fungi, into simpler sugars.

A genus of zygomycetous fungi of the family Mucoraceae, order Mucorales. It is primarily saprophytic, but may cause MUCORMYCOSIS in man from spores germinating in the lungs.

The outermost layer of a cell in most PLANTS; BACTERIA; FUNGI; and ALGAE. The cell wall is usually a rigid structure that lies external to the CELL MEMBRANE, and provides a protective barrier against physical or chemical agents.

Deacetylated CHITIN, a linear polysaccharide of deacetylated beta-1,4-D-glucosamine. It is used in HYDROGEL and to treat WOUNDS.

The N-acetyl derivative of glucosamine.

An insect growth regulator which interferes with the formation of the insect cuticle. It is effective in the control of mosquitoes and flies.

A normally saprophytic mitosporic Chaetothyriales fungal genus. Infections in humans include PHAEOHYPHOMYCOSIS; and PERITONITIS.. Exophiala jeanselmei (previously Phialophora jeanselmei) is an etiological agent of MYCETOMA.

Polysaccharides composed of repeating glucose units. They can consist of branched or unbranched chains in any linkages.

A genus of gram-negative, straight or curved rods which are motile by means of a single, polar flagellum. Members of this genus are found in coastal waters and the open ocean. (From Bergey's Manual of Determinative Bacteriology, 9th ed)

Enzymes that catalyze the transfer of glucose from a nucleoside diphosphate glucose to an acceptor molecule which is frequently another carbohydrate. EC 2.4.1.-.

Proteins found in any species of fungus.

Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.

Pyrimidines with a RIBOSE attached that can be phosphorylated to PYRIMIDINE NUCLEOTIDES.

Amidohydrolases are enzymes that catalyze the hydrolysis of amides and related compounds, playing a crucial role in various biological processes including the breakdown and synthesis of bioactive molecules.

An enzyme that catalyzes the synthesis of fructose-6-phosphate plus GLUTAMINE from GLUTAMATE plus glucosamine-6-phosphate.
