Figure S1. Structural alignment of activated and zymogenic FXIII structure.

Footnotes to Fig S1:Panel A shows the structural alignment graph for the PDB files 4kty and 1f13 created on the FATCAT structural alignment server. The major twists between the two structures are reperesented by arrows in this image. Panel B shows the structurally aligned monomers of zymogenic FXIII (Cyan) and activated FXIII (yellow) depicted in ribbon format (PDB files 1f13 and 4kty respectively). Structural alignment was generated on the TM-align server.

Figure S2. Conservation of the His342 (His342Tyr) residue.

Footnotes to Fig S2: The image shows the multiple alignment of FXIII A subunit with FXIII A from other species and also with other known Transglutaminases. The region of FXIII A shown includes the His342 residue which is highly conserved across both types of alignment.

Figure S3.Aggregation profile for the FXIII A subunit amino acid sequence

Footnotes to Fig S3: The graph shows regions of FXIII A subunit which are more prone to aggregation. The peaks represent highly aggregation prone regions.
Figure S4.Disordered regions in FXIII A subunit amino acid sequence

Footnotes to Fig S4: The image shows the prediction of disordered regions in FXIII A subunit. The peaks represent the degree of disorder. The red line indicates the minimum threshold for identification of a disordered region with a false positive prediction rate of 5%.

Table S1. Atomic details of Hydrogen bonds for the respective residues.

Footnotes to Table S1: The Table lists all the H-bonds/salt bridges (observed in the post simulation averagedzymogenic structure) formed by the residues on which the mutations have been reported in this study.

Table S2. Pathogenicity prediction results for the F13A1 mutations.

Mutation / SNPs&GO / Polyphen-2 / MutPred
Pro166Leu / Neutral / Damaging / Non-Deleterious
Arg171Gln / Disease / Damaging / Non-Deleterious
His342Tyr / Disease / Damaging / Deleterious
Gln415Arg / Neutral / Benign / Non-Deleterious

Footnotes to Table S2: Three pathogenicity predictions servers were queried for the reported mutations [ on 05.02.2013, on 05.02.2013, on 05.02.2013].

Table S3. Prediction of Ubiquitination sites on the mutated FXIII A amino acid sequence.

Footnotes to Table S3: This table lists the predicted Ubiquitination sites in the FXIII A subunit amino acid sequence with their likely possibilities represented as a scoring function. The threshold for this scoring function all across is -1.90.
