Supplementary Material for "Sequence and Structure Classification of Kinases" (JMB, 2002, 320:855-881) and "A Comprehensive Update of the Sequence and Structure Classification of Kinases" (under review). Contents: Directories "ver1" and "ver2" contain lists of accession numbers (gi numbers) for the sequences included in the initial and updated kinase classifications, respectively. These lists were constructed from the non-redundant database of protein sequeces at NCBI in ~June 2001 and July 2004. Each directory also contains a file listing the family numbers and names (ver1/v1_family_key and ver2/v2_family_key). Note that numbering of the families has changed in some cases. The file "table_of_functional_residues.pdf" is a table cataloging key functional residues/motifs in representatives of well-studied kinase families.
