In addition, excess alpha or beta globin chains form unstable tetramers
that cause hemolysis.
aeruginosa dihydropyrimidinase tetramer
. An asymmetric unit contains four crystallographically independent P.
iTAG[TM] HLA-A2/Mart-1 Tetramer
, iTAG HLA-A2/HIV Tetramer
HIV, iTAG [K.sub.b]/OV, and iTAG Db/GagL Tetramer
were purchased from Beckman Coulter.
Other example queries for tetramers
are used in the context of Influenza A virus and associated MHC alleles.
Dinitrogenase, also referred to be MoFe protein or component 1, which is a 220 to 240 kDa tetramer
of the nifD and nfK gene products.
(26) On the other hand, MacKinnon and his group analyzed the structure of a bacterial [K.sup.+] channel, KcsA, with two transmembrane helices and a tetramer
structure, by X-ray crystallography and clearly elucidated the [K.sup.+]-selective mechanism.
Reaction of 8-(dimethyl amino) naphthyl lithium with CuBr in diethyl either was carried out by Erik  and a tetramer
copper complex was obtained.
This form of hemoglobin cannot bind oxygen, and it increases the oxygen affinity of the other heme groups within the hemoglobin tetramer
. Consequently, methemoglobin causes cyanosis and impairs oxygen delivery to tissues.
structure is composed of a dimer of dimers that can be represented by an A-B/B-A symmetry (Fig.
Cells were incubated with major histocompatibility class II tetramers
containing an immunodominant peptide epitope of HKx31 (nucleoprotein, I-[A.sup.b]/[NP.sub.311-325]; NIH Tetramer
Core Facility, http: //tetramer.yerkes.emory.edu/).
