Telomerase reverse trascriptase with RNA and telomeric DNA

Telomerase is an RNA–protein complex (RNP) that extends telomeric DNA at the 3´ ends of chromosomes using its telomerase reverse transcriptase function (TERT) and integral template-containing telomerase RNA (TER).

Pathogenic bacteria fight versus oxidative stress

Chemistry Nobel for mechanistic studies of DNA Repair

Centro activo de la enzima reparadora de errores AlkB (azul y naranja) en el genoma en este caso 1 metil-adenina. Una de las hebras del ADN de doble cadena (amarillo) presenta una adenina metilada (1-meA) un daño común de los genoma. Esta adenina y el grupo metilo (rosa) se muestra como modelo de bolas y palos. El átomo de Hierro II (verde) en este caso está relacionado con la catalisis E. coli AlkB protein is a direct dealkylation DNA repair protein. It perform the oxidative demethylation of DNA base lesions 1-meA, 3-meC, 1-meG and 3-meT. AlkB also removes etheno DNA lesions, by using a similar oxidation mechanism. Human homolog ABH2 has the same role of guarding mammalian genomes against 1-meA damage by repairing this lesion in double-stranded DNA (dsDNA).
