Example sentences for: residues

How can you use “residues” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • It is possible that, in vivo, GSK3β directly phosphorylates serine 33 independently of serine 37, but that both residues must be phosphorylated for transcriptional activation to occur in vivo.

  • Second, amino-acid sequence alignments of the diversified proteins show that these proteins still retain the identity of critical domains, such as signal peptides and transmembrane domains, as well as critical residues in the active sites of enzymes (Table 2and data not shown).

  • Table 3shows the frequency of various amino acid residues occurring in the three categories intermediate, rigid and non-rigid.

  • There are two homologous type IA topoisomerases present in E. coli . Topoisomerase III has potent DNA decatenating activity for resolution of plasmid DNA replication intermediates, but much weaker relaxation activity than topoisomerase I [ 17 ] . To exhibit maximal relaxation activity, topoisomerase III requires high temperature (52°C) along with low magnesium and monovalent ion [ 17 18 ] . In contrast, E. coli topoisomerase I was not active in the in vitro assay for resolution of plasmid DNA replication intermediates [ 19 ] . Removal of the C-terminal 49 amino acids from the 653 amino acid topoisomerase III protein resulted in drastic reduction of catalytic activity [ 20 ] . Fusion of the carboxyl-terminal 312 amino acid residues of E. coli topoisomerase I, which includes the entire ZD domain, onto the 605 N-terminal amino acids of topoisomerase III generated a hybrid topoisomerase that has relaxation activity resembling topoisomerase III along with weak decatenating activity [ 21 ] . Although preferring single-stranded DNA as binding substrate, topoisomerase I had been shown to also bind double-stranded DNA [ 22 ] , but there is no data available to indicate which domain in the enzyme is responsible for this interaction.

  • The interactions of A-4 and A-10 with coat protein involve non-identical contacts with the same five amino acid residues, namely Val29, Thr45, Ser47, Thr59 and Lys61 [ 2, 3].
