Abstract

Figure S2. Relationship between the depth of sequencing and sum of the assembled contigs associated with a species for 225 species. Each panel represents a different species. The y axis represents the nucleotides assembled into contigs associated with a species. The x axis is the estimated number of nucleotide sequences for the species (proportion of the species in the microbiome multiplied by the number of nucleotides sequenced for this sample). The horizontal lines indicate 1 million nucleotides. As represented in the legend, the color of the points relate to the CIM or CEM conditions from which each point originates. (PDF 3014 kb)

Abstract

Figure S4. Proportion of samples and enzymes positive per cluster per condition. For each combination of enzyme clusters and experimental conditions, the proportion of positive enzymes compared to the total size of the combination was calculated. A value of 1 indicates that all samples were positive for all enzymes. A value of 0 indicates that no sample in a given condition was positive for any enzyme from the cluster. (PDF 305 kb)

Abstract

Azidothymidine (AZT) is a widely used inhibitor of type I human immunodeficiency virus (HIV) reverse transcriptase that act as a DNA chain terminator. Studies have shown primer unblocking and rescue of DNA synthesis AZT-resistant HIV-1 reverse transcriptase on DNA and RNA templates. Our recent study showed AZT bindings to the G-C, A-T base pairs and the backbone phosphate group of DNA duplex resulting in partial DNA conformational changes. This study was designed to examine the interaction of AZT with RNA in aqueous solution at physiological condition, using diferent drug/RNA (phosphate) molar ratios of 1/800 to 1/2 and constant RNA concentration of 1.25 or 12.5 mM (phosphate). Capillary electrophoresis, FTIR, and UV-visible difference spectroscopic methods and molecular modeling were used to determine the drug binding sites, binding constants, and the effects of AZT complexation on RNA conformation. Structural analysis showed that AZT binds RNA through G-C and A-U bases with two binding constants of K1 = 7.3 × 105 M–1 and K2 = 1.90 × 105 M–1. The drug distributions were 54% with G-C, 36% A-U, and 10% with the backbone phosphate group. RNA remains in A-family structure and drug sugar pucker in the C2′-endo/anti conformation in the AZT–RNA complexes. Molecular modeling studies show hydrogen bondings between RNA and AZT donor groups.
