In molecular biology, the condensation domain is a protein domain found in many multi-domain enzymes which synthesise peptide antibiotics. This domain catalyses a condensation reaction to form peptide bonds in non-ribosomal peptide biosynthesis. It is usually found to the carboxy side of a phosphopantetheine binding domain (pp-binding). It has been shown that mutations in the HHXXXDG sequence motif in this domain abolish activity suggesting this is part of the active site.[1]

Pfam Clan
This family is a member of clan CoA-acyltrans (CL0149), which has the following description:
All characterised families in this clan are involved in CoA-dependent acyltransferase. All families have a characteristic HXXXD motif.
The clan contains the following 9 members:
2-oxoacid_dh AATase Carn_acyltransf CAT Condensation PapA_C Transferase Tri3 WES_acyltransfAlignments
We store a range of different sequence alignments for families. As well as the seed alignment from which the family is built, we provide the full alignment, generated by searching the sequence database (reference proteomes) using the family HMM. We also generate alignments using four representative proteomes (RP) sets, the UniProtKB sequence database, the NCBI sequence database, and our metagenomics sequence database. More...
View options
We make a range of alignments for each Pfam-A family. You can see a description of each above. You can view these alignments in various ways but please note that some types of alignment are never generated while others may not be available for all families, most commonly because the alignments are too large to handle.

HMM logos is one way of visualising profile HMMs. Logos provide a quick overview of the properties of an HMM in a graphical form. You can see a more detailed description of HMM logos and find out how you can interpret them here. More...
Trees
This page displays the phylogenetic tree for this family's seed alignment. We use FastTree to calculate neighbour join trees with a local bootstrap based on 100 resamples (shown next to the tree nodes). FastTree calculates approximately-maximum-likelihood phylogenetic trees from our seed alignment.
Note: You can also download the data file for the tree.
Curation and family details

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 Condensation domain has been found. There are 78 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 sequence.
