Note: the sequence segments colored grey are disorderd in the protein structure. This generally means they do not contribute significant energy to the fold of the domain. The six histidines at the C-terminus colored in firebrick were added for purification and are not part of the Mbp1 sequence.

Note: here too the C-terminus is disordered and colored grey and the protein has a purification tag colored in firebrick. However, this being an NMR file, disordered segments are included in the PDB coordinate file and defining the extent of disorder required evaluating the superposed set of models. There are no more structured residues than in the 1MB1 structure, even though the sequence used in the experiment was longer.

Note: this sequence is a part of the Saccharomyces cerevisiae Swi6 protein, which is homologous to Mbp1 but does not contain an APSES domain. Its ankyrin domains have been structurally defined in the 1SW6 PDB file, they do not conform in all details to the canonical Ankyrin domain structure. The sequence segments colored grey are disordered in the protein structure.
Annotations
NCBI CDD APSES and KilA-Ndomain boundaries
The APSES domain is a well-defined type of DNA-binding domain that is ubiquitous in fungi and unique in that kingdom. Structurally it is a member of the Winged Helix-Turn-Helix family. Recently it was found that it is homologous to the somewhat shorter, prokaryotic KilA-N domain; thus the APSES domain was retired from pFam and instances were merged into the KilA-N family. However InterPro has a KilA-N entry but still recognizes the APSES domain.
KilA-N domain boundaries in Mbp1 can be derived from the results of a CDD search with the ID 1BM8_A (the Mbp1 DNA binding domain crystal structure). The KilA-N superfamily domain alignment is returned.
- (pfam 04383): KilA-N domain; The amino-terminal module of the D6R/N1R proteins defines a novel, conserved DNA-binding domain (the KilA-N domain) that is found in a wide range of proteins of large bacterial and eukaryotic DNA viruses. The KilA-N domain family also includes the previously defined APSES domain. The KilA-N and APSES domains may also share a common fold with the nucleic acid-binding modules of the LAGLIDADG nucleases and the amino-terminal domains of the tRNA endonuclease.

Note that CDD and SMART are not consistent in how they apply pFam 04383 to the Mbp1 sequence. See annotation below.
The CDD KilA-N domain definition begins at position 16 of the 1BM8 sequence. But virtually all fungal APSES domains have a longer, structurally defined, conserved N-terminus. Blindly applying the KilA-N domain definition to these proteins would lose important information. For most purposes we will prefer the sequence spanned by the 1BM8_A structure. The sequence is given below, the KilA-N domain is coloured dark green. By this definition the APSES domain is 99 amino acids long and comprises residues 4 to 102 of the NP_010227 sequence.

SMART Annotations
A SMART search with the yeast Mbp1 protein sequence retrieved the APSES domain and three regions of similarity to ankyrin domains, annotated a number of low-complexity regions and a stretch of coiled coil. Annotations have been consolidated below.
SAS Annotations
A SAS FASTA search with yeast Mbp1 protein sequence retrieved the homologous Ankyrin sequence from Swi6 (PDB: 1SW6), together with secondary structure annotations. This structural annotation is based on homology to a protein of known structure. Annotations were consolidated into below.
While CDD, SMART and SAS all annotate the same general regions, they disagree in details of the domain boundaries and on the precise alignment.

When considering the relatively high degree of conservation – e.g. there are 34 fully conserved positions (*) in this alignment of 103 positions – keep in mind that this collection of species represents on the order of a billion years of divergent evolution from a common ancestor.
Distant Homologs
APSES domains are a subfamily of Kil-A N domains; the latter include examples:
- in Protists (e.g. Trichomonas vaginalis
XP_001289194) - in DNA viruses (e.g. Canarypox virus
NP_955235) - in Gammaproteobacteria (e.g. Escherichia coli
WP_032936777(KilA))
