Example sentences for: tm-helices

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

  • Although hydrophobic residues such as leucine and isoleucine are among the most abundant residues in TM-helices, they are not well conserved in position.

  • It is known that amino acids are positioned with an average of 3.6 residues per turn in TM-helices [ 20].

  • It contains 12 TM-helices in a homodimer of two 6-TM-helical bundles, which form a central chamber to translocate substrates.

  • By comparing the amino-acid composition of conserved residues in the TM-helices of the transporter-like families with that of the rest of the Pfam-A families (Table 3), we found that glycine is two times more conserved in the transporter-like families, reflecting the favored GxxxG and GxxxxxxG pairs in these families.

  • However, it is unlikely that polytopic membrane domains in the 12-TM Pfam-A families have a structure like that of ABC transporters; as there is no obvious sequence similarity within the sequence containing the 12 TM-helices, it is unlikely to form two 6-TM-helical bundles.
