LITERATURE
a chimeric bifunctional enzyme composing of galactose dehydrogenase from Pseudomonas fluorescens and lactate dehydrogenase from Bacillus stearothermophilus is successfully constructed and expressed in Escherichia coli
-
development of a recombinant yeast exhibiting efficient lactate production by substituting the coding region of PDC1 on chromosome XII for that of LDH through homologous recombination
expressed in Leuconostoc citreum using a shuttle vector pLeuCM, change of the pyruvate carbon flux in Leuconostoc citreum from D-lactate into L-lactate by heterologous expression of L-lactate dehydrogenase
expressed in Saccharomyces cerevisiae replacing disrupted pyruvate decarboxylase 1 and alcohol dehydrogenase 1
-
expression in Escherichia coli
expression in Escherichia coli as maltose-binding protein fusion protein. CpLDH1 is probably evolved from the same ancestor of CpMalDH1 by a very recent gene duplication that occurs after Cryptosporidium parvum diverges from other apocomplexans
-
expression in Escherichia coli HB101 using a pEMBL vector. The gene is strongly expressed in the vector used if the orientation of the insert allows the LDH promoter and the vector's lac promoter to direct transcription in the same direction

gene pfldh, recombinant expression in Saccharomyces cerevisiae, the optimized engineered strain is used as host for L-lactic acid fermentation. Strain IBB10B05 incorporates a NADH-dependent pathway for oxidoreductive xylose assimilation within CEN.PK113-7D background and is additionally evolved for accelerated xylose-to-ethanol fermentation. The pfldh gene is placed in strain IBB10B05 at the pdc1 locus under control of the pdc1 promotor, and strain IBB14LA1_5 additionally has the pdc5 gene disrupted resulting in strain IBB14LA1. The Saccharomyces cerevisiae strain originally optimized for xylose-to-ethanol fermentation is useful to implement L-lactic acid production from glucose and xylose

multiple initiation sites required for transcription of the LDHA gene are identified in its promoter region, including a cAMP response element (CRE) and E-box motif. The LDHA gene promoter possesses also two conserved hypoxia response elements (HREs) containing functionally essential binding sites for hypoxia-inducible factor 1 (HIF-1) with the consensus sequence 5?-RCGTG-3?, which may strongly suggest an oxygendependent regulation of LDH-5 activity
