HP0062 is an 86 residue hypothetical protein from Helicobacter pylori strain 26695. HP0062 was identified ESAT-6/WXG100 superfamily protein based on structure and sequence alignment and also contains leucine zipper domain sequence. Here, we report the sequence-specific backbone resonance assignment of HP0062. About 97.7% of all $^1H_N,;^{15}N,;^{13}C_{alpha},;^{13}C_{eta};and;^{13}C=O$ resonances were assigned unambiguously. We could predict the secondary structure of HP0062 by analyzing the deviation of the $^{13}C_{alpha};and;^{13}C_{eta}$ chemical shifts from their respective random coil values. Secondary structure prediction shows that HP0062 consist of two ${alpha}$-helices. This study is a prerequisite for determining the solution structure of HP0062 and can be used for the study on interaction between HP0062 and DNA and other Helicobacter pylori proteins.
