ubaA

Gene
ubaA
Protein
SAMP-activating enzyme E1
Organism
Haloferax volcanii (strain ATCC 29605 / DSM 3757 / JCM 8879 / NBRC 14742 / NCIMB 2012 / VKM B-1768 / DS2)
Length
270 amino acids
Function
Likely activates multiple ubiquitin-like SAMPs for protein conjugation as well as for sulfur transfer, via ATP-dependent adenylation at their C-terminus. In fact, it is required for the formation of all three SAMP1-, SAMP2- and SAMP3-protein conjugates, and for molybdenum cofactor (MoCo) biosynthesis and thiolation of tRNAs.
Similarity
Belongs to the HesA/MoeB/ThiF family.
