tRNA_anti-like Provide feedback
This is a family of bacterial, archeael and viral proteins that is related to the tRNA_anti family PF01336. The major characteristic of families like tRNA_anti is their OB-fold, and many of them bind DNA.

The OB (oligonucleotide/oligosaccharide binding) was defined by Murzin . The common part of the OB-fold, has a five-stranded beta-sheet coiled to form a closed beta-barrel. This barrel is capped by an alpha-helix located between the third and fourth strands .
The clan contains the following 45 members:BOF CSD DNA_ligase_OB DUF2110 DUF223 DUF3127 DUF35 EFP eIF-1a eIF-5a EutN_CcmL EXOSC1 mRNA_cap_C OB_NTP_bind OB_RNB OmdA Phage_DNA_bind POT1 RecO_N RecO_N_2 Rep-A_N Rep_fac-A_3 Rho_RNA_bind Ribosom_S12_S23 Ribosomal_L2 Ribosomal_S17 RNA_pol_Rbc25 RNA_pol_Rpb8 RuvA_N S1 S1-like S1_2 SSB Stn1 TEBP_beta Ten1 Ten1_2 TOBE TOBE_2 TOBE_3 TRAM tRNA_anti-codon tRNA_anti-like tRNA_anti_2 tRNA_bind
We make a range of alignments for each Pfam-A family:
- the curated alignment from which the HMM for the family is built
- the alignment generated by searching the sequence database using the HMM
- Representative Proteomes (RPs) at 15%, 35%, 55% and 75% co-membership thresholds
- alignment generated by searching the NCBI sequence database using the family HMM
- alignment generated by searching the metagenomics sequence database using the family HMM
You can see the alignments as HTML or in three different sequence viewers:
- Pfam viewer
- an HTML-based viewer that uses DAS to retrieve alignment fragments on request

For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the PDBe group, to allow us to map Pfam domains onto UniProt sequences and three-dimensional protein structures. The table below shows the structures on which the tRNA_anti-like domain has been found. There are 10 instances of this domain found in the PDB. Note that there may be multiple copies of the domain in a single PDB structure, since many structures contain multiple copies of the same protein seqence.
