Example sentences for: quaternary
How can you use “quaternary” in a sentence? Here are some example sentences to help you improve your vocabulary:
Several lines of evidence, including genetic analyses, and similarities in biochemistry and quaternary structures, suggest that the E. coli RecT and phage λ Redβ proteins are functionally equivalent as mediators of single-strand exchange in DNA recombination [ 10 12 ] . However, no sequence similarity has been detected between these proteins leaving their actual evolutionary relationships unresolved.
E174 in ACR3 and S218 in ACR4 are required for catalytic function [ 12 ] . Substitution of H59 in ACR1 converted CD39 into an ADPase in a quaternary structure dependent manner [ 13 ] . Mutation of W187A in ACR3 affected CD39 folding and translocation, while mutation of W459A in ACR5 increased ATPase activity but diminished ADPase activity [ 14 ] . Mutations of D62 and G64 of ACR1 and D219 and G221 of ACR4 demonstrated that the nucleotide phosphate binding domains of NTPDases are similar to those present in the actin/heat shock protein/sugar kinase superfamily [ 15 ] . These results suggest that the conserved residues of the ACR1 to 5 regions are involved in the catalytic mechanism of CD39.
Hypothesized migrations out of northern Asia purportedly occurred along three lines: 1) westward into Europe, with gradual migration into North America, western Asia, Asia Minor, the Mediterranean, and Africa; 2) eastward into Siberia into western North America, and into eastern Europe; and 3) further south into Asia primarily during the Quaternary.
We show that, in spite of the functional similarities, and the similar quaternary structures, there are three distinct superfamilies of SSAPs, namely the RecT/Redβ, RAD52 and ERF, that appear to be evolutionarily unrelated to each other.
S. pombe RNA triphosphatase Pct1 is a 303-amino acid polypeptide with a homodimeric quaternary structure [ 12 ] . The pct1 +gene contains a single intron within the open reading frame [ 12 ] . S. pombe RNA guanylyltransferase Pce1 is a 402-amino acid monomeric protein [ 20 ] ; there are no introns within the pce1 +gene.
