Protein identification is the process of assigning a name to a protein of interest (POI), based on its amino-acid sequence. Typically, only part of the protein’s sequence needs to be determined experimentally in order to identify the protein with reference to databases of protein sequences deduced from the DNA sequences of their genes. Further protein characterization may include confirmation of the actual N- and C-termini of the POI, determination of sequence variants and id… http://www.bushorchimp.com/pz63da7c8-cz59402d7-9002-07-7-sequencing-grade-trypsin-genetically-engineered-methylation-modified-protein-expressed-in-e-coli.html biologi bachelor sduWebNov 14, 2024 · The genome sequence of RGG3 was found in RAP-DB (Os03g0407400).
