CLUSTAL format seed alignment for MF_00533

_____________________________________________________________________________

Features found in the protein:
The following colors are used to highlight features:
blue indicates SIGNAL, PROPEP, TRANSMEM, DOMAIN, ZN_FING, REPEAT,
DNA_BIND and CA_BIND.
magenta is used to display DISULFID, THIOLEST and THIOETH.
red is used for all other features, such as INIT_MET, ACTIVE SITE,
 METAL,BINDING, NP_BIND, SITE, REGION, etc.
The ID of the sequence used as the template for feature propagation is 
underlined.
A '<' at the beginning of a sequence or '>' at the end indicate that
 the protein is fused with another domain either at the N- or C-terminus.
