RH + HBr + H2O2 = RBr + 2 H2O
Brings about the bromination of a range of organic molecules, forming stable C-Br bonds. Can also act on iodide ions. The enzymes of this group contain vanadium (V) bound to the active centre. Since the actual halogenating agents are the respective hypohalous acids, vanadium-containing halide peroxidases lack substrate specificity and regioselectivity.

besides its phytase activity (EC 3.1.3.8) with myo-inositol hexakisphosphate, the enzyme rSt-Phy also shows haloperoxidase activity. Enzyme rSt-Phy brings out a change in color of phenol red from red-orange to blue-violet in the presence of metavanadate ions, H2O2 and KBr in the reaction mixture, which confirms the bromoperoxidation of phenol red. Only histidine acid phosphatases with the active site sequence RHGXRXP can function as haloperoxidase, when vanadate ion is incorporated into the active site. Vanadate is a phosphate analogue, which is generally considered to bind as a transition state analogue to the phosphoryl transfer enzymes and inhibits their activities

vanadate
in the solid state structure, every protein monomer binds one vanadate to the tele imidazole nitrogen of residue His486. In solutions of sodium orthovanadate, isoform apobromoperoxidase II recovers bromoperoxidase activity by one order of magnitude faster than apobromoperoxidase I

Vanadium
-
presence of vanadium coordinated to oxygen/nitrogen either as vanadium(V) (in the native, native plus bromide, and native plus peroxide samples) or vanadium(IV) (in the reduced enzyme). There are structural changes at the metal site on reduction of the native enzyme, notably a lengthening of the average inner-shell distance and the presence of terminal oxygen together with histidine and oxygen-donating residues
Vanadium

the substrate bromide does not bind to active site vanadium but to a light atom, possibly carbon, in its vicinity
Vanadium
the holoenzyme contains trigonal-bipyramidal coordinated vanadium atoms at its two active centres
Vanadium
-
requires vanadium for enzyme activity. The enzyme activity increases ca. 250% with the action of V5+ on the isolated enzyme, since more than 2/3 of the protein molecules are in the apo form. This effect of V5+ addition is inhibited in phosphate buffer, probably because phosphate and vanadate compete for the active site

crystallized from ammonium sulfate solutions in a form suitable for X-ray diffraction analysis. Crystals are grown by the vapour-diffusion technique using the sitting-drop method. X-ray diffraction studies show that the crystals belong to the tetragonal space group P4(1)2(1)2 or P4(3)2(1)2 with a = b = 114.3 and c = 276.0 A. The crystals diffract to at least 2.4 A resolution
structure of the enzyme is solved by single isomorphous replacement anomalous scattering X-ray crystallography at 2.0 A resolution. Crystals of the holoenzyme and the apoenzyme are obtained from 2.1 M ammonium sulfate solutions buffered at pH 8.3 and diffract to 2.4 A resolution. The crystals are stable in the X-ray beam for more than one week. They belong to the tetragonal system, space group P4(3)2(1)2, with lattice constants a ?= 114.3 A,? c = 276.0 A
the crystals exhibit a teardrop morphology and are grown from 2 M ammonium dihydrogen phosphate pH and diffract to beyond 1.7 A resolution. They are in tetragonal space group P4222 with unit-cell dimensions of a = b = 201.9 A, c = 178.19 A, alpha = beta = gamma = 90°
-
sitting drop vapour diffusion method, two crystal forms are obtained, one hexagonal form using ammonium phosphate as precipitant (form 1) and a second cubic vanadium bound form (form 2). The best crystals of the cubic form 2 containing vanadate are only obtained with the wild type enzyme. The optimised conditions use an initial protein concentration of 18 mg/ml in 50 mM Tris-H2SO4, 0.4 M KBr, 1 mM Na3VO4, 20% (w/v) polyethylene glycol 6000. For the wild type enzyme crystals grown in form 2, a mother liquor substituting the precipitant with 25% polyethylene glycol 400 and 25% polyethylene glycol 6000 is used

-
the oligomeric structure of the enzyme is not apparently disrupted by exposure to 60°C. The purified bromoperoxidase at 135 nM is maintained in the absence of any protective reagent at 60°C for 24 h. Within 30 min about 60% of the original activity is lost but no further decline in activity is seen over the full course of the incubation
additional information
-
vanadate increases the thermostability. Ag+ and Al3+ lower the thermostability of the enzyme when compared with the control. Mn2+, Fe2+, Co2+, Ni2+, and Ba2+ have slightly positive effects, whereas Li+, Na+, K+, and Rb+ have no effect and Zn2+ lowers the thermostability

GENERAL STABILITY
ORGANISM
UNIPROT
LITERATURE
activity half-life times increase along the series of buffers: phosphate
-
after treatment with a mixture of chloroform/ethanol the enzyme still shows 65% of its initial brominating activity
-
Ca2+ significantly increased the enzyme stability. Strontium and magnesium ions have similar effects
-
circular dichroism measurements showed that the secondary structure is not affected upon incubation in 4% SDS
-
denaturation did not occur upon incubation in 4 M guanidine hydrochloride
-
dialysis of the enzyme preparation against 1 mM EDTA in 0.1 M citrate-phosphate buffer (pH 3.8) results in loss of enzymic activity. Incubation with vanadium, does not restore the enzymic activity. Also various other metal ions: Zn(II), Fe(II), Cu(II) and Mn(II) are ineffective in the reactivation of the preparation

COMMENTARY
LITERATURE
synthesis
immobilization of enzyme on magnetic micrometre-sized particles in quantitative yields, with up to 40% retention of initial bromoperoxidase activity. The immobilized enzyme is stable with a half-life time of about 160 days. It serves as reusable catalyst for bromide oxidation with H2O2 in up to 14 consecutive experiments. Immobilized enzyme is used for methyl pyrrole-2-carboxylate conversion into derivatives of naturally occurring compounds e.g. from Agelas oroides with product selectivity of up to 75%
