Intensely red, moisture-sensitive crystals of [(TiCl 2 )(1,3-P 2 S 8 )] 2 were obtained by the reaction of TiCl 4 and P 4 S 10 at room temperature. The crystal structure determination revealed molecules formally consisting of two units of the anion [1,3-P 2 S 8 ] 2– connected...
Continuous monitoring of blood/urine glucose level is prerequisite for diabetic patient. In the proposed work we consider the two-dimensional photonic crystal-based biosensor for detecting glucose level in human body. Two-ring resonator structure such as horizontal loop double ring resonator and ...
Figure 1.Schematic depiction of the makorin RING finger protein 3 (MKRN3) structure and location of mutations reported in patients with central precocious puberty. Protein structure: numbers indicate amino acids from 1 to 507. The canonical zinc fingers (C3H) typical of RNA binding activity are...
structure trapped in the process of RING-anchored chain elongation. Together with a kinetic analysis, this reveals how chemical activation of the acceptor ubiquitin is achieved. It also reveals a specific topology of the RING domains that is necessary for formation of the self-anchored ubiquitin ...
In addition, during sporulation, mother cell inhibitor of FtsZ (MciZ) prevents inappropriate cell division once the process has been initiated. Abstract Bacterial cell division is orchestrated by a tubulin homologue, FtsZ, which polymerizes to form a ring-like structure that is both a scaffold ...
In summary, the cryo-EM structure of UBE2R2 bound to CRL2FEM1C illuminates a unique interface between UBE2R2 and FEM1C that is required for rapid priming kinetics of a substrate recruited to this particular CRL-UCE pairing. To assess the structure of UBE2R2-mediated neo-substrate priming, ...
Synthesis of A-ring synthon of 19-NOR-1α,25-dihydroxyvitamin D3 from (D)-glucose The present invention provides a method for the synthesis of an A-ring synthon phosphine oxide used in the preparation of 19-nor vitamin D compounds, and to novel synthetic intermediates formed during the synth...
Structure and Function of PilQ, a Secretin of the DNA Transporter from the Thermophilic Bacterium Thermus thermophilus HB27 Secretins are a family of large bacterial outer membrane protein complexes mediating the transport of complex structures, such as type IV pili, DNA and fil......
Rubrolone A (1) was first reported in 1978 as a red pigment produced by Streptomyces enchinoruber1, and subsequent structure elucidation revealed a nearly coplanar and highly conjugated aglycone consisting of a tropolone ring, a five-membered cyclopentanone, and a pyridine ring2 (Fig. 1). A ...
Glucokinase (sometimes to be abbreviated to GK in the present specification) (EC2.7.1.1) is one of the four kinds of hexokinases found in mammals, and is also called hexokinase IV. GK is an enzyme that catalyzes the conversion of glucose to glucose-6-phosphate, which is the first step of...
