Glyco-Enzyme Repository

Repository of Expression Constructs for Glycosylation Enzymes

Gateway® entry clones and mammalian, baculovirus and bacterial expression constructs for glycosyltransferases, glycoside hydrolases and glycan-modifying enzymes

AMY1A, AMY1B, AMY1C, AMY2A, AMY2B

Alpha-amylase 1

Glycoside hydrolaseClones available from DNASUSource values disagree
Conflicting values in the source site. The original site stated this gene's identity in two places and they do not agree:
  • Gene symbol: the GH13 family index recorded AMY1A/B/C/AMY2A/B, this record recorded AMY1A, AMY1B, AMY1C, AMY2A, AMY2B.
  • NCBI GeneID: the GH13 family index recorded 276/277/278/279/280, this record recorded NP_004029, NP_001008219, NP_001008220, NP_000690, NP_066188, NP_001008222.
Both readings are shown here because the migration does not decide which is right. The construct sequence files are the authority on what is actually in each plasmid. All such cases are listed on the Data Notes page.

Design strategy

How this coding region was truncated for soluble expression. See Construct Design for the strategy behind these choices.

Domain structure / topologyN-term sig seq
Truncation strategy (eukaryotic hosts)N-term deletion/N-term fusion

Gateway® entry clones

Coding regions captured in pDONR221 (or an equivalent synthesised donor). These transfer into any Gateway destination vector by LR recombination, including user-supplied vectors for custom projects.

Baculovirus Expression

Recombinant baculovirus for expression in Sf9 or other lepidopteran insect cells. Virus stocks are supplied by the Jarvis lab, not DNASU.

Ordering. Copy the DNASU clone ID and paste it into the DNASU clone search. Rows marked not yet assigned describe a construct design for which no distributable clone has been deposited. Baculovirus stocks are supplied by the Jarvis lab (dljarvis@uwyo.edu), never by DNASU. A step-by-step walkthrough is on the Tutorial page.
