The renormalization of chiral perturbation theory is carried out to next-tonext-to-leading order in the meson sector. We calculate the divergent part of the generating functional of Green functions of quark currents to O(p6) for chiral SU(n), involving oneand two-loop diagrams. The renormalization group equations for the renormalized low-energy constants of O(p6) are derived. We compare our res...

ZRANB2 is a zinc-finger protein that has been shown to influence alternative splice-site selection. The protein comprises a C-terminal arginine/serine-rich domain that interacts with spliceosomal proteins and two N-terminal RanBP2-type zinc fingers that have been implicated in RNA recognition. The second zinc finger bound to a six-nucleotide single-stranded RNA target sequence crystallized in t...

The homeodomain from the engrailed protein of Drosophila has been crystallized from ammonium phosphate at pH 6.8. The crystals form in space group P6(1)22 (or P6(5)22), with cell dimensions a = b = 44.8 A and c = 118.2 A. These crystals diffract to 1.8 A resolution. A complex containing the engrailed homeodomain and a duplex DNA site also has been crystallized. The cocrystals form in space grou...

Mastoparans are tetradecapeptides found to be the major component of vespid venoms. A mastoparan toxin isolated from the venom of Anterhynchium flavomarginatum micado has been crystallized and X-ray diffraction data collected to 2.7 A resolution using a synchrotron-radiation source. Crystals were determined to belong to the space group P6(2)22 (P6(4)22). This is the first mastoparan to be cryst...

Francisella tularensis, a potential bioweapon, causes a rare infectious disease called tularemia in humans and animals. The macrophage growth locus A (MglA) protein from F. tularensis associates with RNA polymerase to positively regulate the expression of multiple virulence factors that are required for its survival and replication within macrophages. The MglA protein was overproduced in Escher...

Incorporation of Vpx into human immunodeficiency virus type 2 (HIV-2) virus-like particles is mediated by the Gag polyprotein. We have identified residues 15 to 40 of Gag p6 and residues 73 to 89 of Vpx as being necessary for virion incorporation. In addition, we show enhanced in vitro binding of Vpx to a chimeric HIV-1/HIV-2 Gag construct containing residues 2 to 49 of HIV-2 p6 and demonstrate...

Recently, Pei et al. (arXiv2105.13250) reported that ambient pressure ${\beta}$-MoB$_2$ exhibits a phase transition to ${\alpha}$-MoB$_2$ (space group: $P6/mmm$) at P~70 GPa and this high-pressure is high-temperature superconductor exhibited $T_c=32 K$ P~110 GPa. Despite has the same crystalline structure as MgB$_2$2 $T_c$'s of MgB$_2$ are very close, first principles calculations showed in sta...
