Fig. 4 in Molecular and structural characterization of agmatine coumaroyltransferase in Triticeae, the key regulator of hydroxycinnamic acid amide accumulation
Fig. 4. The global structure of apo-TaACT2. (A) Superposition of TaACT2 (cyan) on HvACT (PDB ID 7CYS; light brown) and SbHCT (PDB ID 4KEC; pink). (B) Surface diagram of apo-TaACT2. Domains I, II, and the crossover part are colored in blue, light grey, and yellow, respectively. The black triangle indicates the solvent tunnel. The catalytic center, His153, is shown in red. The molecular graphics were produced by UCSF Chimera (https://www.rbvi.ucsf.edu/ch imera).

Fig. 6. The structure around clade-IV in Molecular and structural characterization of agmatine coumaroyltransferase in Triticeae, the key regulator of hydroxycinnamic acid amide accumulation
Fig. 6. The structure around clade-IV-specific EVDSWL motif. The Glu, Asp, and Trp in the motif of HvACT1-1 (yellow) and TaACT1-1 (cyan) and their corresponding residues in SbHCT (pink; PDB 4KEC), and AtHCT (light grey; PDB 5KJU) are shown with sticks. The catalytic His and the Arg that interact with the carboxy group of shikimate in SbHCT and AtHCT are also shown. Ala360 and 362 of barley and wheat ACTs, respectively, correspond to the Arg in HCTs. p-Coumaroylshikimate molecules bounded to the crystals of SbHCT and AtHCT are presented. Note that the structures of HCTs were those of holoenzymes complexed with a natural product, p-coumaroylshikimate.

Fig. 3 in Molecular and structural characterization of agmatine coumaroyltransferase in Triticeae, the key regulator of hydroxycinnamic acid amide accumulation
Fig. 3. Relative transcription levels of ACTs in barley, wheat, and rice shoots. The absolute quantity of transcripts of HvACT1 (A), HvACT2 (B), TaACT1 (C), TaACT2 (D), OsAHT1 (E), and HmACT (F) was quantified using real-time PCR and normalized to actin level. The relative transcription levels were described as the percentage ratio to HvACT1 at 48 h. The data are shown as means ± standard deviation (n = 6). Different characters of the bars indicate significant differences (p <0.05, Tukey–Kramer test).

Fig. 1. Structure analysis, determined using 15 in Association analysis and molecular tagging of phytochemicals in the endangered medicinal plant licorice (Glycyrrhiza glabra L.)
Fig. 1. Structure analysis, determined using 15 AFLP primer combinations and the STRUCTURE software, of the 170 individual Glycyrrhiza glabra plants sampled in 59 localizations. Sub-populations A and B are represented in green and red color, respectively. Individuals (identified by numbers) are grouped in localizations (identified by L1, L2, etc., and also by the corresponding codes). See Supplementary Table 4 for information on the different localizations.

Carbon fibres from renewable resources: the role of the lignin molecular structure in its blendability with biobased poly(ethylene terephthalate)
<p>Biobased poly(ethylene terephthalate) has been successfully blended with isopropyl alcohol fractioned hardwood organosolv lignin. The blend compatibility was analysed using Gibbs free energy calculations and confirmed by glass transition temperature measurements as well as morphological studies. The carbon fibres obtained from this blend displayed a turbostratic carbon phase and their morphology exhibited a one phase smooth surface. The carbon yield of the blend was found to be improved by fractionation, reaching values of ∼40%. The chemical structure of lignin, most notably the amount of available aromatic hydroxyl groups, was critical for the success of this work. The high molecular weight fraction is enriched with aromatic hydroxyl groups that can crosslink as ether type bonds such as β-O-4 and β-5 bonds. Upon aliphatic hydroxyl substitution in a modified lignin, the blend with BPET was found to be incompatible and produced a carbon fibre exhibiting two phases, low carbon yield and a low amount of the turbostratic phase.</p>
