-   Size: 322 amino acids
-   Molecular mass: 34735 Da
-   Protein Accession: P05089
-   Family: Belongs to the arginase family. Key element of the urea cycle converting L-arginine to urea and L-ornithine, which is further metabolized into metabolites proline and polyamides that drive collagen synthesis and bioenergetic pathways critical for cell proliferation, respectively; the urea cycle takes place primarily in the liver and, to a lesser extent, in the kidneys
-   Domains: Arginase, Ureohydrolase, Ureohydrolase_dom_sf, Ureohydrolase_Mn_BS
-   The protein Rv3899c of Mycobacterium tuberculosis (H37Rv) is identified as a potential vaccine candidate due to its non-toxic, secretory nature with an 'immunoglobulin-like' fold, and its interaction with human leukocyte antigen HLA-DRB1\*04:01, with increased binding affinity upon citrullination of its Arg1 residue [[PMID: 34228167]](https://www.ncbi.nlm.nih.gov/pubmed/34228167).
