Homologous cluster 'HUP domains' representative domains
Cluster description:
HUP domains homologous cluster includes domains with following signatured motifs: PP-loop motif (LSGGxDS for example in ATPases), HIGH and KMSKS motifs (aminoacyl-tRNA synthetases), as well as domains whose signature motifs were degraded, but they have high structure similarity with other HUP domains. Also this cluster includes photolyases-like (cryptochrome) and USPA-like domains, which lack any signature motifs. (Aravind et al., Proteins, 2002; PMID: 12012333)
