NOBS is the main bleach activator used in the U.S.A. and Japan. [4] Compared to TAED, which is the predominant bleach activator used in Europe, NOBS is efficient at much lower temperatures. At 20 °C NOBS is 100 times more soluble than TAED in water. [5]
The perhydroxyl anion then attacks the activator, forming a peroxy acid: HO 2 − + RC(O)X → X − + RC(O)O 2 H The overall reaction of TAED ( 1 ) with 2 equivalents of hydrogen peroxide gives diacetylethylenediamine ( 2 ) and 2 equivalents of peracetic acid ( 3 ):
Activator I was patented by Activator Methods International on September 26, 1978. [4] [7] [8] Activator II was released, with an added "impedance head", in 1994. [4] Activator V is a cordless electric version that gives off no more than 0.3 J of kinetic energy in a 3-millisecond pulse. [4]
Activator may refer to: Activator (genetics) , a DNA-binding protein that regulates one or more genes by increasing the rate of transcription Activator (phosphor) , a type of dopant used in phosphors and scintillators
Peptide-methionine (S)-S-oxide reductase (EC 1.8.4.11, MsrA, methionine sulphoxide reductase A, methionine S-oxide reductase (S-form oxidizing), methionine sulfoxide reductase A, peptide methionine sulfoxide reductase, formerly protein-methionine-S-oxide reductase) is an enzyme with systematic name peptide-L-methionine:thioredoxin-disulfide S-oxidoreductase (L-methionine (S)-S-oxide-forming).
Antithrombin inactivates its physiological target enzymes, Thrombin, Factor Xa and Factor IXa with rate constants of 7–11 x 10 3, 2.5 x 10 3 M −1 s −1 and 1 x 10 M −1 s −1 respectively. [ 5 ] [ 24 ] The rate of antithrombin-thrombin inactivation increases to 1.5 - 4 x 10 7 M −1 s −1 in the presence of heparin, i.e. the reaction is ...
It spans over 160 kbp, has 14 introns and 15 exons. Its mRNA is 3.9 kbp. It has a 5' UTR of 84 bp and a 3' UTR of 1.6 kbp. F13A1 exon(s) [1] 1 code 5' UTR; 2 code activation peptide; 2–4 code β-sandwich; 4–12 code catalytic domain; 12–13 code β-barrel 1; 13–15 code β-barrel 2; B subunit gene is F13B. It is on chromosome 1 at the ...
Catabolite activator protein (CAP; also known as cAMP receptor protein, CRP) is a trans-acting transcriptional activator that exists as a homodimer in solution. Each subunit of CAP is composed of a ligand -binding domain at the N-terminus (CAP N , residues 1–138) and a DNA-binding domain at the C-terminus (DBD, residues 139–209).
