12738-61-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 12738-61-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,7,3 and 8 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 12738-61:
(7*1)+(6*2)+(5*7)+(4*3)+(3*8)+(2*6)+(1*1)=103
103 % 10 = 3
So 12738-61-3 is a valid CAS Registry Number.

The amino acid sequence of stellacyanin (cas 12738-61-3) from the lacquer tree*09/01/2019

SummaryThe complete amino acid sequence of stellacyanin, a blue copper-containing glycoprotein, is presented. The protein has been enzymatically cleaved by trypsin, chymotrypsin, and by the protease from the Staphylococcus aureus strain U8. Stellacyanin consists of a single polypeptide chain of ...detailed

Optical absorption spectra of azurin and stellacyanin (cas 12738-61-3) in glycerol/water and ethylene glycol/water solutions in the temperature range 290-20 K08/30/2019

We have measured the optical absorption spectra of azurin and stellacyanin in the wavelength range 1100-350 nm and in the temperature interval 290–20 K. Samples are protein aqueous solutions containing 65% (v/v) glycerol or ethylene glycol as cryoprotectants and remain homogeneous and transpare...detailed

Affinity labeling of stellacyanin (cas 12738-61-3) by Cr(II) aquo ions08/28/2019

Stellacyanin, the single blue copper protein from Rhusvernicifera, is reduced stoichiometrically by Cr(II)aq ions yielding a 1:1 adduct between the Cr(III) produced and the reduced protein. This Cr(III)-labeled stellacyanin is substitution inert and no significant loss of the label occurs during...detailed

Probing the metal site in Rhus vernicifera stellacyanin (cas 12738-61-3) by Ni(II) substitution and paramagnetic NMR spectroscopy08/24/2019

Stellacyanin from Rhus vernificera is a blue copper protein in which the metal is coordinated to a Cys, two His and a Gln residue. We have studied the Ni(II) derivative of stellacyanin by paramagnetic 1H NMR spectroscopy. The NMR spectrum resembles that of Ni(II) Met121Gln azurin, indicating a s...detailed
