The powers P n are normal subgroups of E(p), and the example groups are E(p,n) = E(p)/P n. E(p,n) has order p n+1 and nilpotency class n, so is a p-group of maximal class. When p = 2, E(2,n) is the dihedral group of order 2 n. When p is odd, both W(2) and E(p,p) are irregular groups of maximal class and order p p+1, but are not isomorphic.
The P-type ATPases, also known as E 1-E 2 ATPases, are a large group of evolutionarily related ion and lipid pumps that are found in bacteria, archaea, and eukaryotes. [1] P-type ATPases are α-helical bundle primary transporters named based upon their ability to catalyze auto- (or self-) phosphorylation (hence P) of a key conserved aspartate residue within the pump and their energy source ...
The hierarchy of scientific classification. Taxonomy mnemonics are used to memorize the scientific classification applied in taxonomy. They are usually constructed with a series of words that begin with the letters KPCOFGS, corresponding to the initials of the primary taxonomic ranks.
Photosystem I [1] is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin. Ultimately, the electrons that are transferred by Photosystem I are used to produce the moderate-energy hydrogen carrier NADPH . [ 2 ]
A finite p-group G is said to be regular if any of the following equivalent (Hall 1959, Ch. 12.4), (Huppert 1967, Kap.III §10) conditions are satisfied: For every a, b in G, there is a c in the derived subgroup H ′ of the subgroup H of G generated by a and b, such that a p · b p = (ab) p · c p.
A descendant tree is a hierarchical structure for visualizing parent-descendant relations between isomorphism classes of finite p-groups. The vertices of a descendant tree are isomorphism classes of finite p-groups. However, a vertex will always be labelled by selecting a representative of the corresponding isomorphism class.
Recall that a finite group is called a p-group if its order is a power of a prime p. A p-group G is called extraspecial if its center Z is cyclic of order p, and the quotient G/Z is a non-trivial elementary abelian p-group. Extraspecial groups of order p 1+2n are often denoted by the symbol p 1+2n. For example, 2 1+24 stands for an extraspecial ...
