Alternative forms of biotin carboxyl carrier protein: biotinylated biotin-carboxyl carrier protein

Summary:
The accB gene encodes the biotin carboxyl carrier protein (BCCP), a component of acetyl CoA carboxylase [Alix89]. AccB is active as a dimer [Cronan01].

The kinetics of the biotinylation reaction have been determined, and the N terminus does not appear to have any role in the modification [Nenortas96]. Biotinylation causes a large structural change in the C-terminal region of the protein [ChapmanSmith97]. Biotinylation results in loss of conformational flexibility of the biotin interaction region [Yao99]; a "thumb" domain comprising amino acids 94-101 fastens the biotin moiety to the surface of the protein [Roberts99a] and this interaction results in increased protein stability [Solbiati02]. This thumb domain is important for acetyl CoA carboxylase activity [Cronan01, Roberts99a]. Unbiotinylated AccB C-terminal domain dimerizes, and biotinylated AccB C-terminal domain is monomeric [ChapmanSmith97].

AccB appears to interact with the C terminus of the BirA biotin ligase [ChapmanSmith01]. The interaction of BirA with AccB BirA-BCCP binding may preclude BirA dimerization and therefore DNA binding and transcriptional repressor activity of BirA [Weaver01].

A crystal structure of the biotinyl domain is presented at 1.8 angstrom resolution [Athappilly95]. An NMR structure of the C-terminal domain has also been determined [Yao97, Roberts99a] and implications with respect to specificity of protein-protein interactions are discussed [Yao97]. Structural characterization of biotin carboxyl carrier protein (BCCP) by circular dichroism indicates that the biotin moiety may be partly engulfed within the protein rather than fully exposed in solution [Fall76]. Secondary structure predictions have been made [Toh93].

Mutation of the MKM biotinylation sequence reveals substrate requirements; the position of the lysine is critical and the flanking methionines are not [Reche98]. Production of a protein with a mutation of the biotinylated lysine residue partially complements the heat sensitivity of another accB mutant, probably due to formation of mutant heterodimers [Cronan01]. A fabE/accB mutation is shown to disrupt biotinylation [Li92d]. E119K and E147K mutant proteins exhibit defects in biotinylation that are due to defects in interaction with BirA, the biotin ligase [ChapmanSmith99b]. Mutation of residue G133, G143, or V146 causes structural disruption of the protein [ChapmanSmith99b]. A linker region N-terminal to the biotinoyl domain is also essential for function (but not required for biotinylation) [Cronan02b]. Mutations in accB or accC suppress the inviability of an htrB mutant at 42 deg, which is due to accumulation of excess phospholipids [Karow92a].

AccB has 57% identity to Anabaena sp. strain PCC 7120 biotin carboxyl carrier protein [Gornicki93] and has similarity to biotin carboxyl carrier proteins from Pseudomonas aeruginosa [Best93], Mycobacterium leprae [Norman94], Mycobacterium tuberculosis [Norman94], Bacillus subtilis [Marini95], Glycine max (soybean) [Reverdatto99], Sulfolobus metallicus [Burton99], Lactobacillus plantarum [Kiatpapan01], Arabidopsis thaliana [Thelen01], and Aquifex aeolicus [Clarke03]. AccB has similarity to the putative protein encoded by ORF2 of Lactobacillus sanfranciscensis DSM20451T [Ehrmann98]. AccB also has similarity to Streptomyces venezuelae ISP5230 JadJ protein, which is involved in biosynthesis of the polyketide antibiotic jadomycin B [Han00]. Pseudomonas aeruginosa AccB functionally complements conditional lethality of an accB mutation in E. coli[Best93].

AccB exhibits an abnormally large apparent molecular weight of 22.5 kDa, compared to the predicted molecular weight of about 16.7 kDa [Li92d].

Purification of AccB is described [Nenortas96].

AccB peptides have been fused to exogenous proteins for use as biotinylation signals that facilitate purification [Weiss94, Sibler99].
