The sole genus in the family Methanospirillaceae whose organisms are progressively motile by means of polar, tufted flagella. They have been isolated from sewage-sludge and pear waste digesters as well as marine and non-marine habitats.

A genus of gram-negative, aerobic, straight, curved, or branched rods which are motile by a single polar flagellum. (From Bergey's Manual of Determinative Bacteriology, 9th ed)

Any member of the class of enzymes that catalyze the cleavage of the substrate and the addition of water to the resulting molecules, e.g., ESTERASES, glycosidases (GLYCOSIDE HYDROLASES), lipases, NUCLEOTIDASES, peptidases (PEPTIDE HYDROLASES), and phosphatases (PHOSPHORIC MONOESTER HYDROLASES). EC 3.

Potent cholinesterase inhibitor used as an insecticide and acaricide.

Cytochrome P450rm from Rhodotorula minuta catalyzes 4-hydroxylation of benzoate. (1/1)

Rhodotorula minuta, a red yeast, produces a cytochrome P450, tentatively named P450rm, catalyzing the formation of isobutene from isovalerate. We found that P450rm interacted with benzoate and the dissociation constant of P450rm for benzoate was 36 microM. A reconstituted system that consisted of purified P450rm and cytochrome P450 reductase catalyzed the 4-hydroxylation of benzoate in addition to the formation of isobutene; the turnover rate was approximately 40 nmol/min/nmol P450rm. The P450rm-monooxygenase system was specific for benzoate and did not catalyze hydroxylation of other aromatic carboxylates. Since only a benzoate 4-hydroxylase that requires tetrahydropteridine has been isolated to date, P450rm appears to be the first isolated cytochrome P450 that acts as a benzoate 4-hydroxylase. The P450rm-monooxygenase system in microsomes of R. minuta might function in the degradation of L-phenylalanine on the pathway to beta-ketoadipate. (+info)

Ectoparasitic Infestations can be caused by various factors such as poor hygiene, close contact with infected individuals, or exposure to areas where the parasites are present. They can be diagnosed through physical examination and medical tests, such as blood tests or skin scrapings.

Treatment for Ectoparasitic Infestations depends on the type of parasite and the severity of the infestation. Common treatments include insecticides, medicated shampoos, and topical creams or lotions. In some cases, oral medications may be prescribed to treat more severe infestations.

Prevention is key in avoiding Ectoparasitic Infestations. This includes practicing good hygiene, using protective clothing and gear when outdoors, and avoiding close contact with individuals who have known infestations. Regularly inspecting and cleaning living spaces can also help prevent the spread of these parasites.

In conclusion, Ectoparasitic Infestations are a common health issue that can cause a range of health problems. Diagnosis and treatment depend on the type of parasite and the severity of the infestation, while prevention involves practicing good hygiene and taking precautions to avoid close contact with individuals who have known infestations.

Symptoms of CPS1 deficiency disease can vary in severity and may include seizures, developmental delays, poor muscle tone, confusion, and psychomotor retardation. The disorder is usually diagnosed in infancy or early childhood, and patients may experience a range of cognitive and physical disabilities. Treatment for CPS1 deficiency disease typically involves a low-protein diet, supplements to reduce ammonia production, and medications to manage symptoms such as seizures and neurological problems. In severe cases, liver transplantation may be necessary.

CPS1 deficiency disease is an autosomal recessive disorder, meaning that patients must inherit two copies of the mutated gene - one from each parent - to develop the condition. Carrier testing and prenatal testing are available for individuals who have a family history of the disorder or are at risk of being carriers. Early detection and treatment can help manage symptoms and prevent complications, but there is currently no cure for CPS1 deficiency disease.

Methods

Compounds that contain (R)-3-amino-4-(2,4,5-trifluorophenyl)butanoic acid substituted with bicyclic amino moiety (2-aza-bicyclo[2.2.1]heptane) were designed using molecular modelling methods, synthesised, and found to be potent DPP-4 (dipeptidyl peptidase-4) inhibitors. (bvsalud.org)
