FIG. 1.

Sequence alignment of β lactamases. Sequence alignment of β lactamases from M. tuberculosis (BLAC), B. licheniformis (BS3), S. albus (ALBS), E. coli (Toho-1 and TEM-1), E. cloacae (NMC-A), P. vulgaris (K1), M. fortuitum (MYC), K. pneumoniae (SHV-1). Green, completely conserved residues; yellow, identical residues; cyan, similar residues. The important residues mentioned in the context are labeled. The residues labeled by asterisks are the equivalents of those indicated significant to the activity.
