Using this relation, by means of successive action of the raising operator a 1 + we can construct Landau levels for electron [18] with energies E n L = s n 2 n v F l H (3). and wave functions ψ n k ( r ) = 2 δ n 0 - 1 s n ϕ n - 1, k ( r ) ϕ n k ( r ).
A four-component wave function of electron-hole relative motion Φ n 1 n 2, being an eigenfunction of (10), can be constructed by successive action of the raising operators b 1 + and b 2 + (see also [20, 21]): Φ n 1 n 2 ( r ) = 2 δ n 1, 0 + δ n 2, 0 - 2 × s n 1 s n 2 ϕ n 1 - 1, n 2 - 1 ( r ) s n 1 ϕ n 1 - 1, n 2 ( r ) s n 2 ϕ n 1, n 2 - 1 ( r ) ϕ n 1 n 2 ( r ).
Aβ is a complex mixture of peptides ranging in size from 37 to 43 amino acids that are cleaved from the amyloid precursor protein by the successive action of aspartyl proteases known as β- and γ-secretase [2].
As known, those duplex reads correspond to an intermediate of miRNA biogenesis in which the miRNA and opposing segment of the hairpin, called the miRNA star (miRNA*), are excised from the hairpin through successive action of Drosha and Dicer RNase III endonucleases [28] [30].
Thus, to the extent a glutenase cocktail could be formulated by combining ASP and DPPIV, it would presumably detoxify gluten in the stomach via the successive action of ASP on intact gluten proteins followed by DPPIV on the peptide generated by ASP.
The ubiquitination cascade requires the successive action of three enzymes.
Additionally, polyketide modules often carry out varying degrees of β-carbon processing by successive action of ketoreductase (KR), dehydratase (DH), and enoyl reductase (ER) domains.
Of note, ornithine could also be generated from proline by p4ha2 (+ 2.27), and putrescine from spermine and spermidine by the successive action of sat1 (+ 1.47) and maoa (+ 2.56).
The Aβ polypeptide is generated by processing of APP, through the successive action of two proteolytic enzymes, β-secretase and γ-secretase [ 2].
