9174192-6	1997	This enzyme differed from TEM-1 (blaT-1B gene) by four amino acid substitutions: Met-->Leu-69, Glu-->Lys-104, Gly-->Ser-238 and Asn-->Asp-276.	Lysine	107-110	hypothetical protein	Escherichia coli	26-31	
8239618-3	1993	Both TEM-10 sequences differed from TEM-1 by substitutions of Ser-162 and Lys-237.	Lysine	74-77	hypothetical protein	Escherichia coli	5-10	
1910040-0	1991	Replacement of lysine 234 affects transition state stabilization in the active site of beta-lactamase TEM1.	Lysine	15-21	hypothetical protein	Escherichia coli	102-106	
1910040-8	1991	Therefore, lysine 234 in the E. coli beta-lactamase TEM-1 is involved both in the initial recognition of the substrate and in transition state stabilization.	Lysine	11-17	hypothetical protein	Escherichia coli	52-57
