Substantia Innominata
|
D013377 |
[Tissue in the BASAL FOREBRAIN inferior to the anterior perforated substance, and anterior to the GLOBUS PALLIDUS and ansa lenticularis. It contains the BASAL NUCLEUS OF MEYNERT.

|
Substantia Nigra
|
D013378 |
[The black substance in the ventral midbrain or the nucleus of cells containing the black substance. These cells produce DOPAMINE, an important neurotransmitter in regulation of the sensorimotor system and mood. The dark colored MELANIN is a by-product of dopamine synthesis.

|
Substrate Cycling
|
D015219 |
[A set of opposing, nonequilibrium reactions catalyzed by different enzymes which act simultaneously, with at least one of the reactions driven by ATP hydrolysis. The results of the cycle are that ATP energy is depleted, heat is produced and no net substrate-to-product conversion is achieved. Examples of substrate cycling are cycling of gluconeogenesis and glycolysis pathways and cycling of the triglycerides and fatty acid pathways. Rates of substrate cycling may be increased many-fold in association with hypermetabolic states resulting from severe burns, cold exposure, hyperthyroidism, or acute exercise.

Substrate Specificity
|
D013379 |
[A characteristic feature of enzyme activity in relation to the kind of substrate on which the enzyme or catalytic molecule reacts.

|
Subtalar Joint
|
D013380 |
[Formed by the articulation of the talus with the calcaneus.

|
Subthalamic Nucleus
|
D020531 |
[Lens-shaped structure on the inner aspect of the INTERNAL CAPSULE. The SUBTHALAMIC NUCLEUS and pathways traversing this region are concerned with the integration of somatic motor function.
] |
|
Subthalamus
|
D020530 |
[A transition zone in the anterior part of the diencephalon interposed between the thalamus, hypothalamus, and tegmentum of the mesencephalon. Components of the subthalamus include the SUBTHALAMIC NUCLEUS, zona incerta, nucleus of field H, and the nucleus of ansa lenticularis. The latter contains the ENTOPEDUNCULAR NUCLEUS.

Subtilisin
|
D020860 |
[A serine endopeptidase isolated from Bacillus subtilis. It hydrolyzes proteins with broad specificity for peptide bonds, and a preference for a large uncharged residue in P1. It also hydrolyzes peptide amides. (From Enzyme Nomenclature, 1992) EC 3.4.21.62.

Subtraction Technique
|
D013382 |
[Combination or superimposition of two images for demonstrating differences between them (e.g., radiograph with contrast vs. one without, radionuclide images using different radionuclides, radiograph vs. radionuclide image) and in the preparation of audiovisual materials (e.g., offsetting identical images, coloring of vessels in angiograms).

Subtractive Hybridization Techniques
|
D066251 |
[Methods of studying differential GENE EXPRESSION of especially low-abundance, tissue-specific gene transcripts.

Suburban Health Services
|
D019036 |
[Health services, public or private, in suburban areas. The services include the promotion of health and the delivery of health care.
] |
|
Suburban Population
|
D013383 |
[The inhabitants of peripheral or adjacent areas of a city or town.
] |
|
Suburethral Slings
|
D053825 |
[Support structures, made from natural or synthetic materials, that are implanted below the URETHRA to treat URINARY STRESS INCONTINENCE.
] |
|
Succimer
|
D004113 |
[A mercaptodicarboxylic acid used as an antidote to heavy metal poisoning because it forms strong chelates with them.
] |
|
Succinate Cytochrome c Oxidoreductase
|
D013384 |
[An electron transport chain complex that catalyzes the transfer of electrons from SUCCINATE to CYTOCHROME C. It includes ELECTRON TRANSPORT COMPLEX II and ELECTRON TRANSPORT COMPLEX III.
] |
|
Succinate Dehydrogenase
|
D013385 |
[A flavoprotein containing oxidoreductase that catalyzes the dehydrogenation of SUCCINATE to fumarate. In most eukaryotic organisms this enzyme is a component of mitochondrial electron transport complex II.
] |
|
Succinate-CoA Ligases
|
D013389 |
[Enzymes that catalyze the first step leading to the oxidation of succinic acid by the reversible formation of succinyl-CoA from succinate and CoA with the concomitant cleavage of ATP to ADP (EC 6.2.1.5) or GTP to GDP (EC 6.2.1.4) and orthophosphate. Itaconate can act instead of succinate and ITP instead of GTP.EC 6.2.1.-.
] |
|
Succinate-Semialdehyde Dehydrogenase
|
D050644 |
[An enzyme that plays a role in the GLUTAMATE and butanoate metabolism pathways by catalyzing the oxidation of succinate semialdehyde to SUCCINATE using NAD+ as a coenzyme. Deficiency of this enzyme, causes 4-hydroxybutyricaciduria, a rare inborn error in the metabolism of the neurotransmitter 4-aminobutyric acid (GABA).
