Two amino acid amidohydrolase genes encoding L-stereospecific carbamoylase and aminoacylase are organized in a common operon in Bacillus stearothermophilus.
Batisse N., Weigel P., Lecocq M., Sakanyan V.
The L-carbamoylase gene (amaB) upstream of the previously detected L-aminoacylase gene (amaA) in the Bacillus stearothermophilus NCIB8224 strain was identified in this study. The amaB and amaA genes are cotranscribed as a single mRNA from the same transcriptional start. The two-ama-gene operon is ... >> More
The L-carbamoylase gene (amaB) upstream of the previously detected L-aminoacylase gene (amaA) in the Bacillus stearothermophilus NCIB8224 strain was identified in this study. The amaB and amaA genes are cotranscribed as a single mRNA from the same transcriptional start. The two-ama-gene operon is conserved in B. stearothermophilus strains. A cross-activity of L-carbamoylase towards respective substrates for L-aminoacylase supports the hypothesis of a common ancestor for both amino acid amidohydrolase genes. << Less

Molecular cloning and biochemical characterization of L-N-carbamoylase from Sinorhizobium meliloti CECT4114.
Martinez-Rodriguez S., Clemente-Jimenez J.M., Rodriguez-Vico F., Las Heras-Vazquez F.J.
An N-carbamoyl-L-amino acid amidohydrolase (L-N-carbamoylase) from Sinorhizobium meliloti CECT 4114 was cloned and expressed in Escherichia coli. The recombinant enzyme catalyzed the hydrolysis of N-carbamoyl alpha-amino acid to the corresponding free amino acid, and its purification has shown it ... >> More
An N-carbamoyl-L-amino acid amidohydrolase (L-N-carbamoylase) from Sinorhizobium meliloti CECT 4114 was cloned and expressed in Escherichia coli. The recombinant enzyme catalyzed the hydrolysis of N-carbamoyl alpha-amino acid to the corresponding free amino acid, and its purification has shown it to be strictly L-specific. The enzyme showed broad substrate specificity, and it is the first L-N-carbamoylase that hydrolyses N-carbamoyl-L-tryptophan as well as N-carbamoyl L-amino acids with aliphatic substituents. The apparent Km values for N-carbamoyl-L-methionine and tryptophan were very similar (0.65 +/-0.09 and 0.69 +/-0.08 mM, respectively), although the rate constant was clearly higher for the L-methionine precursor (14.46 +/- 0.30 s(-1)) than the L-tryptophan one (0.15 +/-0.01 s(-1)). The enzyme also hydrolyzed N-formyl-L-methionine (kcat/Km = 7.10 +/- 2.52 s(-1) x mM(-1)) and N-acetyl-L-methionine (kcat/Km = 12.16 +/-1.93 s(-1) x mM(-1)), but the rate of hydrolysis was lower than for N-carbamoyl-L-methionine (kcat/Km = 21.09 +/-2.85). This is the first L-N-carbamoylase involved in the 'hydantoinase process' that has hydrolyzed N-carbamoyl-L-cysteine, though less efficiently than N-carbamoyl-L-methionine. The enzyme did not hydrolyze ureidosuccinic acid or 3-ureidopropionic acid. The native form of the enzyme was a homodimer with a molecular mass of 90 kDa. The optimum conditions for the enzyme were 60 degrees C and pH 8.0. Enzyme activity required the presence of divalent metal ions such as Ni2+, Mn2+, Co2+ and Fe2+, and five amino acids putatively involved in the metal binding were found in the amino acid sequence. << Less
