Inhibitory effects of 2'-deoxy-L-thymidine 5'-triphosphate (L-dTTP) which is an enantiomer of the natural substrate (D-dTTP) on the activity of mammalian DNA polymerases, Escherichia coli DNA polymerase I and HIV-1 reverse transcriptase were examined. Interestingly, L-dTTP showed remarkable inhibitory effect on HIV-1 reverse transcriptase in competitive fashion with respect to the substrate dTTP. In contrast, eukaryotic cell nuclear DNA polymerases alpha and beta were not or slightly inhibited by L-dTTP.

UI	MeSH Term	Description	Entries
D004256	DNA Polymerase I	A DNA-dependent DNA polymerase characterized in prokaryotes and may be present in higher organisms. It has both 3'-5' and 5'-3' exonuclease activity, but cannot use native double-stranded DNA as template-primer. It is not inhibited by sulfhydryl reagents and is active in both DNA synthesis and repair.

D004926	Escherichia coli	A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc.	Alkalescens-Dispar Group,Bacillus coli,Bacterium coli,Bacterium coli commune,Diffusely Adherent Escherichia coli,E coli,EAggEC,Enteroaggregative Escherichia coli,Enterococcus coli,Diffusely Adherent E. coli,Enteroaggregative E. coli,Enteroinvasive E. coli,Enteroinvasive Escherichia coli
