Ribosome self-assembly leads to overlapping reproduction cycles and increases growth rate [PDF]

open access: yesarXiv, 2018
In permissive environments, E. coli can double its dry mass every 21 minutes. During this time, ribosomes, RNA polymerases, and the proteome are all doubled. Yet, the question of how to relate bacterial doubling time to other biologically relevant time scales in the growth process remains illusive, due to the complex temporal nesting pattern of these ...

ARISA data from the human gut microbiome can detect individual differences observed by 454 sequencing regardless of binning strategy [PDF]

open access: yesarXiv, 2012
ARISA (Automated Ribosomal Intergenic Spacer Analysis) is a low-cost technique that allows for the rapid comparison of different microbial environments. In this study, we asked if a set of ARISA profiles can distinguish human microbial environments from one another with the same accuracy as results generated from 454 high throughput DNA sequencing ...

Computer simulations of the bacterial ribosome using a general purpose coarse-grained model MARTINI [PDF]

open access: yesarXiv
Ribosomes are critical biomolecular nanomachines responsible for protein synthesis in all known organisms. The function and dynamics of ribosomes can be studied using molecular dynamics computer simulations. Although this task remains challenging at atomic level, several studies have reported all-atom molecular dynamics simulations of the entire ...

MOLECULAR IDENTIFICATION OF SEVERAL CLINICALLYIMPORTANT BACTERIA INCLUDING ENTEROBACTERIA BYPARTIAL 16S RIBOSOMAL RNA GENE SEQUENCE COMPARISON

open access: yesZdravniški Vestnik, 2008
BACKGROUND The correct identification of bacterial isolates is paramount for the correct diagnosis andtreatment of patients. The standard approach for bacterial identification relies on phenotypic tests, which are often time-consuming and unreliable when
