Biotin
Avidin
Carbon-Nitrogen Ligases
Streptavidin
A 60-kDa extracellular protein of Streptomyces avidinii with four high-affinity biotin binding sites. Unlike AVIDIN, streptavidin has a near neutral isoelectric point and is free of carbohydrate side chains.
Methylmalonyl-CoA Decarboxylase
Pyruvate Carboxylase
Valerates
Biotinidase
An enzyme which catalyzes the release of BIOTIN from biocytin. In human, defects in the enzyme are the cause of the organic acidemia MULTIPLE CARBOXYLASE DEFICIENCY or BIOTINIDASE DEFICIENCY.
Carbon-Carbon Ligases
Acetyl-CoA Carboxylase
Fatty Acid Synthase, Type II
The form of fatty acid synthase complex found in BACTERIA; FUNGI; and PLANTS. Catalytic steps are like the animal form but the protein structure is different with dissociated enzymes encoded by separate genes. It is a target of some ANTI-INFECTIVE AGENTS which result in disruption of the CELL MEMBRANE and CELL WALL.
Carboxyl and Carbamoyl Transferases
Pimelic Acids
Hoof and Claw
Multiple Carboxylase Deficiency
A deficiency in the activities of biotin-dependent enzymes (propionyl-CoA carboxylase, methylcrotonyl-CoA carboxylase, and PYRUVATE CARBOXYLASE) due to one of two defects in BIOTIN metabolism. The neonatal form is due to HOLOCARBOXYLASE SYNTHETASE DEFICIENCY. The late-onset form is due to BIOTINIDASE DEFICIENCY.
Egg White
Biotinidase Deficiency
The late onset form of MULTIPLE CARBOXYLASE DEFICIENCY (deficiency of the activities of biotin-dependent enzymes propionyl-CoA carboxylase, methylcrotonyl-CoA carboxylase, and PYRUVATE CARBOXYLASE) due to a defect or deficiency in biotinidase which is essential for recycling BIOTIN.
Vitamin B Deficiency
Carboxy-Lyases
Ligases
Escherichia coli
A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc.
Pantothenic Acid
Holocarboxylase Synthetase Deficiency
The neonatal form of MULTIPLE CARBOXYLASE DEFICIENCY that is caused by a defect or deficiency in holocarboxylase synthetase. HLCS is the enzyme that covalently links biotin to the biotin dependent carboxylases (propionyl-CoA-carboxylase, pyruvate carboxylase, and beta-methylcrotonyl-CoA carboxylase).
