UniProtKB/Swiss-Prot Q9NS18: Variant p.Lys95Glu

Glutaredoxin-2, mitochondrial
Gene: GLRX2
Chromosomal location: 1q31.2-q31.3
Variant information

Variant position:  95
The position of the amino-acid change on the UniProtKB canonical protein sequence.

Type of variant:  Polymorphism
The variants are classified into three categories: Disease, Polymorphism and Unclassified.
  • Disease: Variants implicated in disease according to literature reports.
  • Polymorphism: Variants not reported to be implicated in disease.
  • Unclassified: Variants with uncertain implication in disease according to literature reports. Evidence against or in favor of a pathogenic role is limited and/or conflicting.

Residue change:  From Lysine (K) to Glutamate (E) at position 95 (K95E, p.Lys95Glu).
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 large size and basic (K) to medium size and acidic (E)
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).

Sequence information

Variant position:  95
The position of the amino-acid change on the UniProtKB canonical protein sequence.

Protein sequence length:  164
The length of the canonical sequence.

Location on the sequence:   TSCSYCTMAKKLFHDMNVNY  K VVELDLLEYGNQFQDALYKM
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.

TypePositionsDescription
Chain 20 – 164 Glutaredoxin-2, mitochondrial
Domain 57 – 157 Glutaredoxin
Binding site 109 – 109 Glutathione
Modified residue 77 – 77 S-glutathionyl cysteine; alternate
Mutagenesis 78 – 78 S -> P. Specifically increases the specific activity but decreases affinity for glutathionylated substrates.
Mutagenesis 80 – 80 C -> S. Strongly impairs enzymatic activity.
Beta strand 95 – 98
