Alkaline phosphatase, acid phosphatase, leucine arylamidase, and jV-acteyl-P-glucosaminidase (NAGase) were the only enzymes available for analysis.

Plates were read after approximately 24 hours of incubation, at which time rapid biochemical tests, such as coagulase, catalase, and pyrrolidonyl arylamidase (PYR, Remel, Lenexa, KS), were performed and the identification was released in the EHR.
Leucine arylamidase and valine arylamidase detected was strong for all strains tested, However, valine and cystine arylamidase activities were very low or absent in some strains of Lactococcus.
optochin, bile solubility, and pyrrolidonyl arylamidase tests) (25).
Now, Key characters are used for species and subspecies identification include colony morphology, oxygen requirements, coagulase, clumping factor, heat-stable nuclease, hemolysins, catalase, oxidase, alkaline phosphatase, urease, ornithine decarboxylase, pyrrolidonyl arylamidase, [beta]- galactosidase, acetoin production, nitrate reduction, esculin hydrolysis and aerobic acid production from a variety of carbohydrates including D-trehalose, Dmannitol, D-mannose, D-turanose, D-xylose, D-cellobiose, L-arabinose, maltose, -lactose, sucrose, and raffinose, and intrinsic resistance to novobiocin and polymyxin B [7].
Because of the broad specificity of the substrates, there has been some confusion concerning nomenclature: Serum aminopeptidase is also called leucine aminopeptidase (LAP, the term we use here), alanine aminopeptidase (AAP), aminopeptidase N, aminopeptidase (microsomal), or arylamidase.
The bacteria produced acid from arabinose, glucose, mannose, and xylose, was negative for glycerol fermentation and leucine arylamidase and positive for rhamnose fermentation.
max] values for rat and human liver microsomal arylamidase toward CDEPA was calculated using a Lineweaver-Burke double reciprocal plot.
Isolates were identified as GAS on the basis of p-hemolysis, Gram staining, negative catalase test result, positive pyrrolidonyl arylamidase test result, and agglutination with Lancefield group A antiserum.
All 4 isolates were [alpha]-glucosidase positive and 3 were alanylphenyl-alanyl-proline arylamidase positive.
Only large colony--forming [beta]-hemolytic streptococci were selected and Lancefield grouped by using a Streptococcal Grouping Kit (Oxoid Diagnostic Reagents, Basingstoke, United Kingdora); suspected GAS isolates were tested for pyrrolidonyl arylamidase.
