MeSH

A genus of gram-positive, coccoid bacteria mainly isolated from milk and milk products. These bacteria are also found in plants and nonsterile frozen and dry foods. Previously thought to be a member of the genus STREPTOCOCCUS (group N), it is now recognized as a separate genus.

Year introduced: 1992

A non-pathogenic species of LACTOCOCCUS found in DAIRY PRODUCTS and responsible for the souring of MILK and the production of LACTIC ACID.

Year introduced: 1992(1972)

amino acid sequence given in first source; a lantibiotic; GenBank X71410 (L. lactis)

Date introduced: September 3, 1993

catalyzes the breakage of eight bonds and formation of six bonds in the synthesis of lacticin 481 from the LctA prepeptide; has been sequenced

Date introduced: February 18, 2004

Date introduced: May 31, 2000

amino acid sequence in first source; GenBank AJ011960

Date introduced: February 25, 2000

Group II intron-interrupted relaxase; mediates the initiation of conjugal transfer of plasmid pRS01 possibly by introducing a single-stranded nick at the potential origin of transfer, in order to initiate single strand transfer from donor to recipient; the gene encoding this protein is interrupted by a group II intoron, Ll.ltrB; amino acid sequence in first source

Date introduced: July 26, 1996

a multifunctional protein that promotes group II intron splicing and mobility by acting both on RNA and DNA; it has reverse transcriptase for intron duplication maturase to promote splicing, and DNA endonuclease for site-specific cleavage of recipient alleles; isolated from Lactococci lactis; amino acid sequence in first source; Do not confuse with MatR protein, a transcriptional regulator of malonate metabolism

Date introduced: July 26, 1996

from Lactococcus lactis; amino acid sequence given in first source; GenBank U05215

Date introduced: May 18, 1994

Anti-Bacterial Agents

Date introduced: November 9, 2010

catalyzes conversion of beta-D-glucose-1-phosphate to beta-D-glucose-6-phosphate

Date introduced: August 16, 2006

a glycine-betaine transporter; amino acid sequence in first source; homologies found in many bacterial species

Date introduced: September 5, 2000

a bacterial ABC transporter; amino acid sequence in first source; GenBank AAF04258

Date introduced: November 8, 1999

may be involved in regulating isoleucine biosynthesis; isolated from Lactococcus lactis; amino acid sequence in first source; GenBank U92974; do not confuse with AldR protein

Date introduced: October 31, 1997
