Variant information Variant position:

46 The position of the amino-acid change on the UniProtKB canonical protein sequence.
Type of variant:

LB/B The variants are classified into three categories: LP/P, LB/B and US.

LP/P: likely pathogenic or pathogenic.
LB/B: likely benign or benign.
US: uncertain significance

Residue change:

From Serine (S) to Asparagine (N) at position 46 (S46N, p.Ser46Asn). Indicates the amino acid change of the variant. The one-letter and three-letter codes for amino acids used in UniProtKB/Swiss-Prot are those adopted by the commission on Biochemical Nomenclature of the IUPAC-IUB.
Physico-chemical properties:

Change from small size and polar (S) to medium size and polar (N) The physico-chemical property of the reference and variant residues and the change implicated.
BLOSUM score:

1 The score within a Blosum matrix for the corresponding wild-type to variant amino acid change. The log-odds score measures the logarithm for the ratio of the likelihood of two amino acids appearing by chance. The Blosum62 substitution matrix is used. This substitution matrix contains scores for all possible exchanges of one amino acid with another:

Lowest score: -4 (low probability of substitution).
Highest score: 11 (high probability of substitution).

Polymorphism:

Variability among SIRT6 alleles may account for variations in life span (PubMed:25541994). A minor allele (rs107251) is associated with a decreased life span of 5.5 and 5.9 years when homozygous (TT); when compared to the major allele homozygous (CC) and heterozygous (CT) genotypes, respectively (PubMed:25541994). Additional information on the polymorphism described.
Variant description:

Does not affect histone deacetylase activity. Any additional useful information about the variant.

Sequence information Variant position:

46 The position of the amino-acid change on the UniProtKB canonical protein sequence.
Protein sequence length:

355 The length of the canonical sequence.
Location on the sequence:

PPEELERKVWELARLVWQSS S VVFHTGAGISTASGIPDFRG The residue change on the sequence. Unless the variant is located at the beginning or at the end of the protein sequence, both residues upstream (20) and downstream (20) of the variant will be shown.
Residue conservation:

The multiple alignment of the region surrounding the variant against various orthologous sequences.

Sequence annotation in neighborhood:

The regions or sites of interest surrounding the variant. In general the features listed are posttranslational modifications, binding sites, enzyme active sites, local secondary structure or other characteristics reported in the cited references. The "Sequence annotation in neighborhood" lines have a fixed format:

Type: the type of sequence feature.
Positions: endpoints of the sequence feature.
Description: contains additional information about the feature.

Type	Positions	Description
Chain	2 – 355	NAD-dependent protein deacylase sirtuin-6
Domain	27 – 272	Deacetylase sirtuin-type
Binding site	53 – 53
Binding site	57 – 57
Binding site	64 – 64
Binding site	65 – 65
Modified residue	33 – 33	N6-acetyllysine
Mutagenesis	33 – 33	K -> Q. Mimics acetylation, leading to impaired ability to recognize and bind double-strand breaks (DSBs) sites.
Mutagenesis	33 – 33	K -> R. Decreased acetylation level.
Mutagenesis	45 – 45	S -> A. In AAA mutant; strongly decreased nucleosome-binding; when associated with 206-A--A-208.
Mutagenesis	56 – 56	S -> Y. Abolished NAD-dependent protein deacetylase, defatty-acylase and mono-ADP-ribosyltransferase activities.
Mutagenesis	60 – 60	G -> A. Does not affect the NAD-dependent protein defatty-acylase activity. Abolished NAD-dependent protein deacetylase and mono-ADP-ribosyltransferase activities.
Mutagenesis	65 – 65	R -> A. Does not affect the mono-ADP-ribosyltransferase activity. Abolished NAD-dependent protein deacetylase and defatty-acylase activities.
Beta strand	45 – 51
