PROSITE documentation PDOC51817 [for PROSITE entry PS51817]Peptidase family A3B domain profile
Rice tungro bacilliform virus (RTBV) is a pararetrovirus, and a member of the family Caulimoviridae in the genus Tungrovirus [E1]. RTBV has a long open reading frame that encodes a large polyprotein (P3). P3 contains a putative movement protein (MP), the capsid protein (CP), the aspartate protease (PR) and the reverse transcriptase (RT) with a ribonuclease H activity. PR is a member of the cluster of retroviral proteases and serves to proteolytically process P3. The sequence DSGS is believed to be the RTBV protease active site [1]. The RTBV PR domain forms peptidase family A3 subfamily B [E2].
The profile we developed covers the entire peptidase family A3B domain.
