In enzymology, a 4-hydroxy-3-methylbut-2-en-1-yl diphosphate synthase (HMB-PP synthase, IspG, EC 1.17.7.1) is an enzyme that catalyzes the chemical reaction 2-C-methyl-D-erythritol 2,4-cyclodiphosphate + protein-dithiol ⇌ {\displaystyle \rightleftharpoons } (E)-4-hydroxy-3-methylbut-2-en-1-yl diphosphate + H 2 O + protein-disulfide
The vapor is heavier than air, so it can accumulate at low points. It is explosive at concentrations between 1.4 and 11.4%. [16] Concentrations in the air high enough to be flammable are intolerable to humans due to the irritating nature of the vapor. [12] Butanone fires should be extinguished with carbon dioxide, dry agents, or alcohol ...
Ribbon diagram of myoglobin bound to haem (sticks) and oxygen (red spheres) (Ribbon diagrams, also known as Richardson diagrams, are 3D schematic representations of protein structure and are one of the most common methods of protein depiction used today. The ribbon depicts the general course and organization of the protein backbone in 3D and ...
[3] HMB-PP is the physiological activator ("phosphoantigen") for human Vγ9/Vδ2 T cells, the major γδ T cell population in peripheral blood. With a bioactivity of 0.1 nM it is 10,000-10,000,000 times more potent than any other natural compound, such as IPP or alkyl amines. HMB-PP functions in this capacity by binding the B30.2 domain of ...
HPPD also catalyzes the conversion of phenylpyruvate to 2-hydroxyphenylacetate and the conversion of α-ketoisocaproate to β-hydroxy β-methylbutyrate. [2] [3] HPPD is an enzyme that is found in nearly all aerobic forms of life. [4] This reaction shows the conversion of 4-hydroxyphenylpyruvate into homogentisate by HPPD.
Acetoin, also known as 3-hydroxybutanone or acetyl methyl carbinol, is an organic compound with the formula CH 3 CH(OH)C(O)CH 3. It is a colorless liquid with a pleasant, buttery odor. It is chiral .
4-Hydroxy-tetrahydrodipicolinate synthase (EC 4.3.3.7, dihydrodipicolinate synthase, dihydropicolinate synthetase, dihydrodipicolinic acid synthase, L-aspartate-4-semialdehyde hydro-lyase (adding pyruvate and cyclizing), dapA (gene)) is an enzyme with the systematic name L-aspartate-4-semialdehyde hydro-lyase (adding pyruvate and cyclizing; (4S)-4-hydroxy-2,3,4,5-tetrahydro-(2S)-dipicolinate ...
