The comparison of 1H-NMR spectra of 9 and 8 showed similarities, except for a methine signal at δ 4.36 (br s, W1/2 = 22.3 Hz) in compound 9 which appeared at δ 3.73 in metabolite 8.
This resolution is accordant with the general morphological similarities except for differences in the morphology of the indusia between Nothoperanema and Diacalpe/ Peranema[ 10].
Indeed, some sequences have essentially no sequence level similarities except for a few strictly conserved residues like the catalytically active cysteine.
One might not expect the EC classification to be a good similarity measure in terms of binding, since it does not closely reflect evolutionary or mechanistic similarities except for the case of identical subclasses with different serial numbers.
PiRNAs are very diverse: hundreds of thousands of unique piRNA sequences do not show any structure or sequence motif similarities, except for a bias for a uridine residue at the first base (Le Thomas et al., 2014).
For most pARTs, the amino acid sequences encoded by exons upstream of this phase 0 intron do not show any detectable similarities, except for members of a particular subgroup.
The 138 intron sequences of the 22 genes (PAL gene do not have introns) were aligned between spruce and pine; sequence similarity ranged quite broadly among homologous introns.We observed that highly conserved introns generally were short, and that longer introns had highly variables levels of sequence similarity, except for two introns that were both long and highly conserved.
Although both AM2 and BM2 are proton-selective ion channels, they share little sequence similarity except for the HXXXW sequence, which suggests that their proton conductance properties might differ.
comm).. Pulsed-field gel electrophoresis (PFGE) analysis of XbaI-digested DNA of the 35 isolates obtained from Sicily showed identical or similar profiles that differed from each other by 2 5 bands (>79% similarity), except for the profile obtained from the soft cheese isolate (<40% similarity) (3 ).
In conclusion, across the different TMHs and helix 8, there is no apparent consensus about which template has the highest sequence similarity (except for hRHO)–see Figure S2.
