  Acknowledgments We thank our colleagues who have contributed to our understanding of the histone acetyltransferase and the structure and function of APC/C, and apologize to those whose work we were unable to cite here. We thank J. Rajan Prabu for making the movies showing APC/C conformational ch

  2021-06-05

  

  FOX proteins constitute a large class of transcription factors with multiple functions, from development and organogenesis to regulation of metabolic and immune functions. The Fox transcription factor is characterized by a 100-amino-acid wing helix or forkhead DNA-binding domain. In addition, the FO

  2021-06-05

  

  The differences between ground and transition state properties are exemplified by a comparison of our human–yeast results with those of a structural study of possible differences in ubiquitin-Uba-1 binding in yeast (known structure) with human (simulated in [12]). Their discussion focuses on Ubiquit

  2021-06-05

  

  Verapamil, a calcium channel blocker used clinically as a coronary vasodilator, was amongst the first compounds identified that could reverse MDR and potentiate the effects of MDR1 substrates such as vincristine [15], [16]. Verapamil, along with a number of other MDR1 blockers, have proved largely u

  2021-06-05

  

  In studies directed toward the development of sequence-specific major-groove binding small Peramivir synthesis [11], we desired a non-intercalating molecular scaffold that could direct attached moieties into the major groove. As an initial step toward this goal, we wished to study the DNA binding m

  2021-06-05

  

  The possibility that a carboxyl group attached to the or position of an -arylaminomethylenemalonate ester would lead to increased selectivity for DHODH has been tested and found not to be the case. Indeed, reduced selectivity compared with the corresponding ester is observed and is attributed to a

• The first example of a broadly acting antiviral drug

  2021-06-05

  

  The first example of a broadly-acting antiviral drug is ribavirin, a nucleoside analogue that was proposed to act directly at the level of the viral polymerase, although an indirect effect via inhibition of the host-cell IMP dehydrogenase and depletion of the GTP pool seems more plausible [9]. Anoth

  2021-06-05

  

  MTX and MTXPGs block the activity of the key enzyme DHFR (Fig. 1), which converts folates to their active forms – dihydrofolate (DHF) and tetrahydrofolate (THF). MTXPGs also potently inhibit thymidylate synthase (TS). Furthermore, during dTMP synthesis, TS utilizes the cofactor 5,10-methylene THF, w

  2021-06-05

  

  Studies on the external dehydrogenases of N. crassa have shown that the NDE1 protein is a Ca2+-dependent external NADPH dehydrogenase, while NDE2 is characterized as a dehydrogenase oxidizing both cytosolic substrates (external NADH and/or NADPH) (Carneiro et al., 2004, Melo et al., 2001). All three

  2021-06-05

  

  Although PQQ has nutritional importance and pharmacological effects in higher organisms, including humans [15], until recently, there was no clear evidence for the use of PQQ as a co-factor in a eukaryotic enzyme. This review presents a novel eukaryotic PQQ-dependent quinohemoprotein recently discov

  2021-06-05

  

  DNA promoter hypermethylation is an important mechanism in epigenetic modulation of gene expression.[16], [17], [18] When the promoter CpG island of a gene is hypermethylated, the transcription and its associated function of the gene will be subsequently altered.[19], [20], [21] In human cancers, we

  The annotation is arguably the most important part of analysis, as it enables one to evaluate and interpret the content of the transcriptome assembly. In this context, the non-redundant contigs were initially run in BLAST against the Nr database showing that 55% of them displayed high similarity to

  2021-06-05

  

  Previous studies revealed the expression of the CCR3 receptor in neurons and its neuroprotective function using mice lacking CCR3 expression (Wainwright et al., 2009). The regulation of CCR3 receptor expression in the microglia and astrocytes was shown in neurological disorders and has been demonstr

  2021-06-04

  

  Our approach relied on measurement of bulk solute diffusivity in the three tissue types of interest. Our diffusivity values (Table 3) are on the order of 10−6 cm2/s and are comparable to the PG diffusion coefficient in water at infinite dilution, which is about 10−5 cm2/s at room temperature, as wel

  2021-06-04

  

  Partial suppression of the cot-1 (ts) phenotype by deletion of gul-1 has been well documented (Seiler et al., 2006). This is now also very clearly evident in the transcriptional profile of the various strains (Fig. 2). Furthermore, the comparative analysis of the single and double mutants revealed,
