چکیده

The major objective of this paper is to introduce a novel method for the functional annotation of genes. Our method is based on a graph theoretical measure we call joint betweenness, which is an extension of the well known betweenness centrality measure, involving pairs of genes. We apply our method to the transcriptional regulatory network of yeast to, first, provide a large scale proof of concept of our method and, second, make predictions about the biological function of previously unknown genes.

Initiation of Ageing Process by Meiotic and Mitotic Recombination within the Ribosomal DNA Genes in Saccharomyces cerevisiae

In the budding yeast of Saccharomyces cerevisiae the tandem repeated of rDNA genes are located onchromosome XII, which is in the nucleolus. There are different types of proteins in the nucleoluskeleton,silencing proteins have got important role in nucleolus.It is shown that meiotic recombination between nonsister chromatids in the rDNA genes are stronglysuppressed, and s...

A Re-Annotation of the Saccharomyces Cerevisiae Genome

Discrepancies in gene and orphan number indicated by previous analyses suggest that S. cerevisiae would benefit from a consistent re-annotation. In this analysis three new genes are identified and 46 alterations to gene coordinates are described. 370 ORFs are defined as totally spurious ORFs which should be disregarded. At least a further 193 genes could be described as very hypothetical, based...

Systematic condition-dependent annotation of metabolic genes.

The task of deriving a functional annotation for genes is complex as their involvement in various processes depends on multiple factors such as environmental conditions and genetic backup mechanisms. This study employs a large-scale model of the metabolism of Saccharomyces cerevisiae to investigate the function of yeast genes and derive a condition-dependent annotation (CDA) for their involveme...

EXPRESSION OF HEPATITIS B SURFACE ANTIGEN IN SACCHAROMYCES CEREVISIAE

The genome of HB V virus of serotype ayw cloned in pBR322 and expression shuttle vector p YES2 were used for construction of the HBsAg chimeric genes and their expression in Saccharomyces cerevisiae. Two recombinant plasmids were constructed. One of them contained the coding sequences for the major polypeptide of surface antigen. Another construct carried the major polypeptide with the pre-S2 a...

Effect of Saccharomyces Cerevisiae Yeast and Butyrate Monoglycerides on Performance, Blood Parameters and Nutrients Digestibility in Holstein Suckling Calves

    The aim of this study was to investigate the effects of saccharomyces cerevisiae yeast and butyrate monoglycerides on the performance, blood parameters and nutrients digestibility in suckling Holstein calves. For this experiment, 32 newly-born Holstein calves (average age 1-8 days; average weight 38±1 kg) were used in a completely randomized design with 2×2 factorial arrangement, 4 treatmen...
